Table error correctable, 2 awarded as 3?

[jdw3018]

I don't want to highjack this thread, but what about a scenario where the officials really goof - the shot comes from the border area between coverages of the C and T, and T signals 3 while C clearly signals 2 points to the scorer (I know, this isn't an official mechanic).

Regardless of which on the scorer sees and records, is this a correctable error situation or a bookkeeping error?

I'd think correctable error, as one of the officials made the mistake, but curious if anyone else has a different take?
