If nobody would refer to the last quarter note of 3+3+2/8 as “the third beat” then that’s because it would tend to be confusing.
I disagree. There are two different musical situations where this can occur: 3+3+2 is a pretty common idiom of a three-part *rhythm* against a 2-part *metre*, and here it would in fact be confusing to refer to the "2" as the third beat. Other music may well treat this as beats in their own right, and then everybody would talk about it as three "beats".
It is probably clearer when shown with a less idiomatic example. Consider a 9/8 time signature with a 2,2,2,3 beatStructure. Here it is clear that you'd refer to the groups as four "beats".
