Did the run count?

We had a relatively unusual occurance in my daughters game this evening. The girls in this league are in the 12-14 year old range.

The situation is our team had a runner on third with two outs. The batter hits a fly toward the right fielder and initially does not run out the hit. The fielder attempts to make a play but drops the ball. The runner then takes off for first and is called out, however the runner on third crossed the plate before the third out is called. Does the run count?

Thanks for any thoughts in advance.
