Getting a third out on a time play and then a fourth out on a force play (or, in the case we brought up, BR before 1B) is covered in a baseball case play somewhere. The play I remember is:

Abel on 3B, Baker on 2B, 2 out. Charles grounds to F5, who opts to tag Baker coming to 3B. Abel scores. F5 tags Baker for the 3rd out, then throws to 1B in time to get Charles. Ruling was 4th out on Charles is recognized, no run. I would apply the same to softball.

In the original play in question, apparently the passing of the runner is the third out whether intentional or not, and it negates the force play, creating a time play on the run from 3B. It seems unfair to me, but the run has to score.
