[SCRIPT] Why is this not functioning correctly?

I doubt the game is renaming the newly-created entity but that the game is searching for the entity in some kind of order-by-creation list, therefore the one in the map first is the one found first when calling SetEntityActive. Try using a local map variable of type int to keep track of the number of orbs created, so that you can increment the name of the orb.
