Well I don´t think that other tools from other game do some kind of auto-scripting (perhaps only some default stuff like triggering doors or whatever). The Aurora Editor of Neverwinter Nights e.g has its own scripting engine and you also have to learn the language and script by yourself (or copy the scripts from the web). If you want to create interaktivity in a game's mod you need to learn the scripting language of that game. Otherwise you can only build some (boring) levels with some default monsters.
