Here's what I have:
Pure result of the play is a 2 point TD by B. (AR 8-3-2-III). However, after COP we have a foul by A for continued participation (9-1-17), at the B30. After a COP, penalties against either team are declined by rule (8-3-4-a), and no exceptions apply (Penalties for flagrant personal fouls, unsportsmanlike conduct fouls, dead-ball personal fouls and live-ball fouls treated as dead-ball fouls are enforced on the succeeding kickoff or at the succeeding spot in extra periods.)
So, the 2 points count, move on to KO.
