Some 28 of the squad, including Murray, toured with Scotland during the quadrangular tournament in South Africa in the summer.
Scotland Head Coach Scott Johnson said: "This squad is about getting the job right for our upcoming Test matches but it's also about the next 24 months as we build towards Rugby World Cup 2015."
Murray has started three matches for Warriors this season and has racked-up 18 appearances for the club since his move from Newcastle Falcons last autumn.
