force out oppose to tag out

No, as long as the last out is a force or the BR not making first the run doesn't score.

Just an observation ...this general concept of "force out and stepping on the base" seems to come up regularly in a variety of situations.

Seems like the confustion arises because while everyone understands that if it's a force play you can get the out by stepping on the base many will incorrectly assume the reverse of that statement is true --

that if you get the out by stepping on the base it must have been a force play.

-or- if you got the out by NOT stepping on the base that it WASN'T a force play.

Neither statement is true.

It is my understandnig the use of the word force is meant to mean that the runner is FORCED to advance not the mannor in which he is put out. If the runner is FORCED to advance, then he can be put out by tagging the base or the runner. In other words if you tag the runner before he gets to first, he was still forced out because he was forced to advance.

No run can score on the 3rd out if that out is a force out. Now had the batter/runner reached 1st and made a turn and was then tagged out, even though it was the 3rd out, any run that scored prior to the batter/runner being put out (not a force once he reached 1st) would count.
