I cannot reproduce the error ...
I load the November updated usps.php module into:
/includes/modules/shipping
I REMOVE my existing one ...
I INSTALL and configure the United States Postal Service usps shipping module and everything is working right now ...
For giggles and grins ... close your browser windows, clear your cache ... Reload the file to the server and confirm that the date on the server for the file changes ... REMOVE the existing usps module ... INSTALL the usps module ... configure it ...
Does it like you now?
