Are you sure about the names? You can use the Print() or the AddDebugMessage() function to check if the script is loaded at all (just call it from OnEnter()). For the first one, you'll have to check the log file, so make it print something distinctive, like:
Print("---------------------------- OnEnter() function -------------------------------");

AddDebugMessage() func should display something on the screen if the script get's called, and debug messages are enabled.

If any of these is shown, then the script is executed, but there's some other subtle problem.
Also, if are you loading a saved game? This can sometimes cause strange behavior when the map is sitll being developed - have you tried reloading the map from the debug menu?
