That will list files multiple times if they were modified in more than
one commit. And really, there's no need to walk the history. You really
are just comparing against two points (your baseline and your current
state). Walking the history will also erroneously include files which
changed, but then reverted back to their original state (though I expect
that is the uncommon case).

How about:

  # mark our start point for this and future releases
  git tag baseline `git rev-list HEAD | tail -n 1`

  # find files which differ between then and now; but we only need
  # to care about added and modified files, since deleted ones
  # don't need to be shipped
  git diff --diff-filter=AM --raw baseline HEAD | awk '{print $6}' >files

  # and archive
  git archive --format=zip HEAD `cat files`

You can even use diff's "-z" option if you have filenames that are hard
to quote, but I will leave that as an exercise to the reader.
