  sz() { REPLY=${(l.4..0.)${#REPLY}} }
  print -l ${^MATCHES}(o+sz[1])

Note you'll need the MATCHES to be the actual path to the file since
glob qualifiers only work on real files.

There's a really nasty trick that doesn't require them to correspond to files, which you'll hate.  I think you can combine it into a single expression, but it's bad enough in two.

  local min
  min=(${${(o)${MATCHES//?/\?}}[1]})
  print -l ${MATCHES:#^${~min}}

I'm sure it's completely obvious what this is doing.  It's been posted before.
