Possible 2 out timing play

[rleakins]

I had the below situation at a high school game. I ruled no run contiues play on the batter no force out.

2 outs r1 on first, B1 at the plate, ball hit in gap, R1 rounds third touches home. B1 is thrown out at 3rd. Is this a timing play? and does the run score. High School rules.
