“Compiled Script” vs. “compiled script”
Chris Nebel (who should know):
There is no difference between “Compiled Script” and “compiled script”. The idea that one does resource-fork and one does data-fork is a myth.
I must admit to believing in this myth, but testing with Script Editor and Super Get Info confirms what he says. The best way to make resource-fork compiled scripts is with Script Debugger, though according to Nebel you should also be able to duplicate and then edit an existing resource-fork script. Why not just use a data-fork script? Because some applications don’t yet support them.
