I've been having the same problems in testing a client's site. If you're using the test server, the USPS docs seem to indicate that it only accepts certain specific canned requests. For example, the test requests for domestic rates are listed at:
http://www.usps.com/webtools/htm/Rat...m#_Toc87669085
As I modified my test order to match their parameters, my returned error messages kept changing to match whatever was the first mismatched value. I'd suspect there wouldn't be any issues once you went live (YMMV) as long as you can get back a response from the USPS servers.
Hopes this helps,
-Ken
