Hi Chris,
during a WMS request the GetMap machinery sets some environment variables
that you can pick, using the env function,
to know the scale denominator:
http://docs.geoserver.org/stable/en/user/styling/sld/extensions/substitution.html#predefined-variables
There is no such a thing as a "zoom level" in WMS, but if you really need
that number you can probably
compare the scale denominator with a table of values to get the closest
matching z value
Cheers
Andrea
