Hi,
this is my personal opinion:
reading otherone scripts is the hell on earth. Before I try to understand someones logic I programmed everything myself a dozen of times.
What you could do is: Use the script that covers most of your project and then rewrite the stuff that you need from the other. Implementing to scripts that are not your own will a) take ages, b) be frustating and c) not teach you anything. And espacially the last point is important for you and your next projects.
