So you need to do something before instance gets terminated? Scalr would not terminate your instance until amount of instance in a role is more than Min Instances setting. So, if you want to have exclusive control over termination, set MinInstances to some high value.
We're going to introduce beforeHostTerminate, beforeInstanceLaunch events for scripting in next few days, so you'll be able to execute any code on instance, role or entire farm before Scalr terminates any instance in the role.
