It appears that level scripting isn't that hard coded!
For Mudokons, the value about voicePitch is rescueID. Not all Muds have it, most will have it as 0. The last value for Portals is a Mudokon rescueID too, and so is the value after background in Path Blockers (Slam Doors).

When a Mudokon with a rescueID is rescued (No matter via which portal), portals sharing this ID will disappear (Will no longer reappear), and slam doors sharing this value will open. This is probably the same with many other objects. I believe levers work similarly. I might figure out teleporters soon.

Edit: Solved levers and teleporters.
