The former Magpies boss has been coaching Sunderlands strikers over the past few weeks, and now steps into a bigger role in coaching the reserves.
Ricky Sbragia departed Sunderland to team up with Manchester United this week, and Scott stepped into his role straight away.
The Scotsman took Notts to 8th in his first and only full season in charge, and were 15th when he departed in October 2001 and was replaced by Gary Brazil.
