Do you know JavaScript or C++? If you know them, It won't be hard to learn random map scripting. If you don't, You can still understand most parts of the code as they have comments to explain most parts of the code. And I suggest you to use notepad++ if your OS is windows. Try this and if you still had problems, PM me and I'll answer your questions. Also it is not very hard to learn JavaScript. I know a very good website to learn JS. Click Here.
