at this moment I don't see a way to integrate a point system with games... just because most of them have no built-in mechanism for storing high scores. Also there is no way to establish a communication between your site and an unknown flash game (if you are not the author of that game of course). So, if you need games that can be integrated with your point system, you should contact games authors for making a custom build of their games specially for your site.
And there is no way to get the source files of each game existed in my game packs because sources are intellectual property of those games' authors. As far as I know it costs $2000-5000 to build a quality game from scratch, so you can consider that sum as an average cost of a game's sources. But in any case you should ask each game's author for sources, not me.
But not everything is that bad
Currently I'm working on the Mochiads game feeds' integration into the script. As you maybe know those games supports unified high score tables and challenges... It's not what you need exactly, but very close.
