Maybe it's sufficient to ask: what would be useful for developers to keep score of in order to improve professionally? Surgeons keep score by measuring patient outcomes in order to draw conclusions about their own performance, the effect of which is to "shrink the outliers" - people see where they can improve and they go ask their colleagues, "hey, how'd you do that?". So what would the equivalent of that be for a developer? The best tool I can think of for this isn't an automated system for scorekeeping - it's soliciting feedback [1]. You ask a more seasoned dev who is familiar with your work where you can improve. How do you "shrink the outliers" on a team of developers? Get people to work together. Take each other's code apart.
