Sane implementation of find_scope_members_tags()

Disclaimer: I have absolutely no idea how the original function works.
After gazing into the code for one hour, I just gave up and wrote my own
version of it based on what I think the function should do
but maybe I'm just missing something what justifies the original
implementation's insanity.
