I won't comment :)
Have you tried var EXTERNAL_NET [$DMZ_NET,!$HOME_NET] ?
Like your DMZ_NET is in included in your HOME_NET I am guessing it stops
its test at !$HOME_NET and won't look at what is in your $DMZ_NET.. 
This will require to look at the source to be certain.. or to test it.

Thanks,
Eric
