Is this the behavior that you're thinking of? http://support.microsoft.com/default.aspx?scid=kb;en-us;196500
If so, I wonder what value you would get if it were prioritized on the networks running today? BIND development decided it wasn't something that belonged on the server last I checked. DNS is not necessarily site aware. The clients are, and they query DNS for the site information. So if you ask for an address for a DC, you'll look in your site configuration vs. relying on DNS to give it back in a particular order IIRC.

I've read where AD DNS will sort replies to A record requests based on the IP address of the caller. The idea being that if multiple A records exist for a name, the first in the list will be "closest" to the caller. Makes sense, but I've never seen any documentation on how the comparison is done. Does the DNS server do a simple IP subnet match (same subnet = close, different subnet = not close)? Or, is the DNS server site aware so that it will sort first an address in the same site even if it's a different subnet?
