I reason it into correctable error as follows:

FTs should have been B then A.

A has taken FTs.

Now we realize B needs to take FTs, so B has not been awarded merited FTs - this is correctable.

We award B their merited FTs.

We re-start at POI, B gets ball, free to run baseline.

Hawks Coach, I agree with your reasoning on this play. However, if the officials don't realize the mistake until after all free-throws are attempted, then it does not fit any of the correctable error categories. Funny that whether or not it is a correctable error depends on the time that the officials realize the mistake!

The NCAA ruling is complicated by the POI, whereas in NFHS you wouldn't care what order they were taken in and just administer the division line throw-in (see the casebook play on shooting free-throws in the wrong order).
Therefore, I also believe that you are correct that what happened with the last free throw for the personal foul determines whether or not you use the AP arrow. If it was good, give the ball to the opponent and no arrow, but if missed you have to use the arrow, since neither team got a chance at the rebound.
