Scott led Scotland in two memorable seven-a-side performances in May 2009: they reached the Cup last four of an IRB world series tournament for the first time when they beat Portugal 22-21 in the Twickenham quarter-final round, and they matched that a week later at Murrayfield with a last-eight win against Samoa by 14-12 before going down in an extra-time semi-final defeat by South Africa, the series champions.
He captained the Scots in all but one of the eight tournaments in the IRBís 2006-2007 sevens World Series, injury keeping him out of the South African event. Beginning in that sevens series, under his command the Scots reached the cup quarter-finals in nine successive tournaments.
Scottís first appearance for the Scotland seven was as a late squad replacement for the IRB tournaments in New Zealand and the USA in February 2006. He helped the Scots to bring home the bowl from both competitions before returning to play in the Hong Kong and Singapore events.
He led the Rugby Ecosse Scotland squad in the Singapore tournament in October 2007 and he continued as Scotland captain throughout 2007-2008 IRB tournaments, leading the squad to the Plate final in the final round at Murrayfield in June. A week after the Australian tournament at Adelaide in April 2008 he led the Scottish Thistles to victory in the Melrose clubís 125th anniversary sevens, and in November that year he again led the Scottish Thistles, this time in their Shield tournament success in the Singapore international sevens.
An ankle injury forced him to miss the subsequent first four tournaments of the IRB Sevens World Series, but he had recovered in time to be recalled to the squad in March 2009 for the RWC Sevens in Dubai, where Scotland won the Plate competition. He then took over as captain against for the IRB events in Hong and Adelaide (Australia).
Scott made his debut for Border Reivers as a replacement in the Magners League match against Newport Gwent Dragons at Rodney Parade in January 2007. He joined Glasgow Warriors from Glasgow Hawks in 2005 and moved on to an apprentice contract with Reivers a year later, when he also switched club association from Glasgow Hawks to Hawick: he moved again in 2007, this time to Ayr.
Scott has played for Scotland at under-19 and under-21 levels as well as the Scotland seven. His under-19 internationals were in 2003, including world championship matches in France. He was with Cambuslang at that time, but he moved to Glasgow Hawks the following season, making his first XV debut in the BT Cup quarter-final match against Currie at Malleny Park. He was named man of the match in the cup semi-final against Melrose and was awarded a spot in the starting line-up in the side who beat Dundee HSFP in the 2004 final at Murrayfield.
His Scotland under-21 debut was as a replacement in the 2004 world championship match against England at Galashiels. He played in four of those world championship games and extended the under-21 sequence by playing in the 2005 internationals against France, Ireland, Italy, Wales, and England. He was named man of the match in the Falkirk game in which the Scots beat the Irish for the first time at that level, and later in the year he was in the squad who finished sixth in the under-21 world championship in Mendoza, Argentina. Scott, a former Pupil of Hamilton College, visited New Zealand with the Glasgow Thistles in 2001.
He has a Strathclyde University degree in sport and exercise science.
In the 2009/2010 draft he was allocated to Currie.
