The word "justice" being the keyword (now, for some people) for DEI indicates it is precisely about punishment. At least to those who frame it in terms of "justice". I see that word and I know it is a buzzword for angry people. In the 90s when I was first persuaded as to the necessities of policies that instantiate reverse racial discrimination (i.e. affirmative action) talk was more about equality and unity, and increasing efficiency of the system. Blacks were (still are) not utilized to their full potential, so aa offered a common good inthe form of a more productive, better functioning society. I don't encounter those arguments as much niw as arguments about "justice" or the impossible to define "equity" (not the same as the phrase "equality of outcome" which was a very concrete and useful construct for thinking about racism). Historical context is everything.

What do you do when both A and B score a 95 and there is only one job?

That's what DEI solves for. Not "higher a lesser candidate," but "when both candidates are equal, use diversity of the company when making the final decision"
