People were kind enough to help the other day but I still can't get my head around a suggested solution.
I think I made things a little more complicated than they needed to be so I've attached a simplified version.

Here's the deal:
I have one list of names/score/age group
I want to produce a three sets of results based on age group (A, B or C in column "C")

Believe me, I've tried, but there comes a point where my brainpower isn't up to the task involved.

Anyway, as ever, help would be really appreciated.
