THanks, John, I'm sure you're right actually. So I've just written my matching function like this:

(lambda (f) (string-match (concat "\\\(" fname "\\\)\\\([^[:alnum:]]\\\)*" lname) f))

and if that has a nil result:

(lambda (f) (string-match (concat "\\\(" nname "\\\)\\\([^[:alnum:]]\\\)*" lname) f))

That seems to work pretty well so far.  And as you suggest, I've written a simple function that calls read-file-name for org-attach-attach in the appropriate directory -- though it' s extremely simple, it makes manual attachment much quicker when my brain starts to get foggy from grading papers.

I would not do that if I were you. The fuzzy match might inadvertently
send feed back to the wrong student. I would fall back to some manual
attachment if you do not find an exact match, e.g. using helm or ivy to
select the files for attachment, perhaps sorted and matched using their
fuzzy algorithms.
