What do you mean by "lowest actor"?
One way to do it would be to basically use text to make lists within the lists. For example, you could store "Actor1 5" and "Actor2 10", where the second number is the priority level. Then, you can convert that text to a list itself, compare the priority levels and then create the corresponding actor. I do a somewhat similar idea in my "Demo- Actorless Card Duel", which you can find in the games section of the StencylForge.
