Properties *are* version-controlled. Revision properties aren't, but
svn:mime-type isn't a rev prop. Furthermore, if you look at the help
for svn propset, you'll see that ps without the --revprop flag only
accepts PATHs as an argument, so you have to check out a working copy.
Not to say it can't be done, but your hook script will both create
additional revisions and need to manage working copies.

IIRC, everything without a text/* mime-type will get treated as binary
so just look for non-text mime-types:

find . -! -path '*/.svn/*' -type f | \
  | xargs svn propget "svn:mime-type" 2>/dev/null | grep -v 'text/'
