Table error correctable, 2 awarded as 3?

This play occurred in a recent D-2 game (California, PA vs. Alaska-Anchorage), reported to me by a good friend and fellow official from western Pennsylvania. Arts was involved in a play during the first half that led to the scoring error. He made a 19-foot jumper from the right wing that was clearly signaled as a two-point basket by the officials. However, the official scorer, located on the opposite side of the court, credited Arts with a three-pointer, trimming Cal's lead to 18-16 with 6:22 remaining. The mistake wasn't brought to the attention of the official scorer until halftime and was deemed uncorrectable.

Is this different from signaling 3 for a known 2, or vice versa? Does this error have the typical timeframe associated with it? Rule 2-10-1-e and 2-10-2 and 2-10-3 limit the time to correct.

Is there a different rule here for NCAA men than NFHS?
