As you can see, my tests was indeed with IIS7.5 as well, but PHP 5.4 from the
trunk. The things happening on your server look like a configuration issue.
What you could do
* try another IIS instance, may be on your localhost
* try 5.4 trunk as well
* check that IIS doesn't drop any headers
* ask for help in the mailing lists

I cannot reproduce the issue, tried with the latest php 5.4 and IIS7. IIS7 has
compression turned off and the php.ini has both zlib.output_compression=on and
zlib.output_compression_level=-1 set. The page is merely a phpinfo() page. Here
the simple ping pong:

The output compression seems to work.

Could you please try such a simple page scenario and post the request/response
headers?

I can confirm that WordPress 3.3.1 does not set zlib.output_compression. Looks
like WP never has.
