Make sure the extendedglob option is on:

                 setopt extendedglob

and use

                 matched=(${(M)array:#(#i)*$patt*})

That should work fine; apart from glob qualifiers, which can't be used
with patterns whatever effect they have, about the only things limited
to filename globbing are things that really only apply to files.
