As others have alluded, this concept is fraught with unintended traps. There are countless scenarios of how this score will disadvantage even some of those it is intended to advantage. The underlying factors are much more complex than an algorithm can capture.
Like every other effort to level the playing field, someone has to be disadvantaged for another to be advantaged. In the name of fairness these efforts are deployed, and unfairness is a result. Just against a different group of people.
