Florida vs Puerto Rico LL game

[PSUchem]

Yup, just came on here to see if anyone else watched it.

Situation (if I remember correctly): R1 on 3B and R2 on 2B, 1 out. B3 bunts. Someone (F1? F3? F5? I can't remember) fields the ball, checks the runner, and throws out B3 on a very close play. Fielder at 1B throws home, not in time to get R1. Meanwhile, R2 moves up to 3B. B3, never looks at U1, and doesn't see his sell "out". 1B coach is a player, so no help here. Seeing the ball go to HP, B3 takes off for 2B, drawing the throw from the catcher, where U2 calls B3 out again. (Apparently, B3 wasn't the only one that did not see U1's call.) R2 runs home and scores before a late throw to the plate. Confusion ensues. 3 outs were called, but 2 of them on the same runner.

As you say, unless LL rules differ from ASA, there could have only been 2 possible outcomes:

1) They deemed interference on the already retired runner, in which case the runner on 3B should have been declared out as well, for the 3rd out of the inning.

2) They did not deem interference, rather DMC, and allow the run to stand.

Actual ruling (presumably, based on announcers and mic'ed umpire conversations): Interference on the batter-runner after already being retired, placed R2 back on 3B.

WTF?
