The scores in the ruleset looks fine to me. In the rules, metro bought 5 reward store traits as an example, and only 1 reward store trait (never weary) cost more then 2500 points. The other 4 reward traits cost less than 2500 points.
Hence -
4 reward trait less than 2500 = 4 X 1 point = 4 points
1 reward trait more than 2500 = 1 X 2 points = 2 points
Aspiration completion trait are worth 3 points each.
