I looked briefly at the Lander high score stuff a while back and I don't remember much about it and I can't help you with it specifically. But if you're interested, I've created an ActiveX control to handle high score processing. The main difference is that mine uses a text file (the file name is one of the properties that you set) to store/maintain the scores. It has a few other options as well. It's still pretty much a "beta" version so if you have any suggestions or find any bugs please let me know.
Anyway, if you're interested, here it is...
