    I'm trying to come up with a script that will identify key lookups that have a certain percentage of the query cost. Like if the key lookup is 50% of the query cost then I want the result set.

    I'd probably not go down the route of looking at the costs and just look for Key lookups . But the following should help you get started on putting something together:

    This has a great explanation and is focused on just getting the key lookups:
