Does this run score...

[SamNVa]

I'm sure this has been discussed before, but I can't remember what the consensus was.

Situation: 2 outs, bases loaded. BR hits a homerun. All runners are basically standing around watching the ball instead of running like they're supposed to. BR rounds 1st and passes R3 standing about 10 feet off the base BEFORE R1 has touched the plate. After the pass, all runners continue and complete their trip around the bases.

The question: Do you count R1's run anyway since she was forced home by the BR touching 1st? Or is this strictly a timing play and the run would not score, since the 3rd out was made prior to the touch?
