Hello, I am fairly new with python, and I noticed that the Shuffle type only randomly slects a few types of games. I was wondering how I can edit the python so that it will include all types of games (including the player made and custom mode ones (like orbital ring, fantasy realm, etc.).

It doesn't look like that map script does anything but provide a "generic" random fractal map (rather than specifying grains, it rolls dice for them). It doesn't import or reference any other mapscripts. Someone with more knowledge about python (and/or maps) might be able to whip something up for you.
