I've now added the promised Part 2 of my Building a platform game - a beginner's guide
It covers scoring and, in particular, shows how the score can take account of the particular location where each event happens, and award different numbers of points for each location (e.g. depending on the difficulty of getting there).
I'm always happy to have feedback - especially if you have better ways of doing things!
Part 3 is in the works at the moment, but is unlikely to be added till after the Rotary Competition ;) But when it is is, I'll use this topic to let you know.
