[Lua/Bug/Improvement] Abolish or revamp the 'scores' behavior attribute
scores behavior attribute seems to be in effect, but it's very unclear (undocumented) with how it works and how much impact it has.
I believe it is an interesting mechanic to have, but I also feel like all there is to it in the code is leftover bits that aren't used anymore by most modules of the game. (i.e.: It feels like it's only used in places where it has been forgotten to be removed, which makes things work wonky)
So in that light, I'd like to ask for a decision as to whether the mechanic should be kept (but revamped/updated), or simply removed. To be investigated.
