To the date, there is no strong evidence regarding the usage of score, in stead of "your bitcomet score = platinum" events at MWO. (I'm not playing that so don't ask me bout it ok).
But if u look close enough, you will see the connection between score, exp bar, and ranks (title), whereas the higher your rank, the more resources you will get. Again refer to my post. You can get more info in one of the links there.
Betul, betul, betul.
