Most of scripts are quite camera-independent, for example time-lapses, bracketings, motion detection. Some special scripts that operate on memory adresses or specyfic camera functions (also strange buttons and so on) might work only on a few cameras.
Even when one script can't run on your camera it should just fail, very rare it might crash camera (which mean something like immediately turning off without retracting lens). These situations are rather not dangerous.
If a script is doing something very, very strange, like directly moving a lens or poke something to memory it should be said that's camera specyfic. Then it's good idea to think twice and maybe ask on the forum, if you really can/need to use it.
But once again - most of 'usual' scripts are compatible with most cameras. If one is not - it should be written somewhere near the source code (on wiki) or the file (on forum).
