Runner at 3rd..... 1 out ........ batter pops ball up 25 feet into foul ground on the first base side about 15-20 feet behind the first base bag. Second baseman comes across and makes the catch running into the out of play fence, out of view of the plate (blocked by dugout). As the second baseman turns and runs to get back into view of home plate, the runner at third comes home. Bang, bang play at the plate, runner safe. Is this a sacrifice fly? If not how is it scored? Runner comes home "on the throw"?

It sounds like a sacrifice fly if the runner on third tagged up on the play and was safe at home on the fly out.

To me, this only applies if the runner advanced when the ball is thrown to another base. For example, a batter-runner advancing to second on a single when the left fielder throws the ball home, missing the cutoff, trying to get the lead runner.
