By trial and error what I meant was to set your perl script to write the
scale to say, your Apache log or web log, or some temp file, every time
the script runs.  Zoom in N times and you've got a list of scales from
the maximum down to a far as your zoom. Then use those values in your
map file.

Re: the label. You can easily create two layers, one with no lablel for
your maximum to mid scale. And one with a label for the smaller scales.
