If your mother qualifies for this visa she can stay in Scotland for 5 years if she is a commonwealth citizen now. After 5 years she can apply for permanent residency if she has been employed for all of the 5 years.

You don't say what country your mother is a citizen of. If she isn't a commonwealth citizen she is out of luck
