USPS issues

[icecold]

Hi,

I am having problems with USPS, as the values estimated by the module are substantially less than the actual values, what can be wrong? I noticed there is a patch for 1.3x with slight differences with the usps.php module in version 1.38a, for instance this a code difference:

This is the code in May 2008 patch

 $this->intl_types = array(
        'Global Express' => 'Global Express Guaranteed',
        'Global Express Non-Doc Rect' => 'Global Express Guaranteed Non-Document Rectangular',
        'Global Express Non-Doc Non-Rect' => 'Global Express Guaranteed Non-Document Non-Rectangular',
        'Global Express Envelopes' => 'USPS GXG Envelopes',
        'Express Mail Int' => 'Express Mail International (EMS)',
        'Express Mail Int Flat Rate Env' => 'Express Mail International (EMS) Flat-Rate Envelope',
        'Priority Mail International' => 'Priority Mail International',
        'Priority Mail Int Flat Rate Env' => 'Priority Mail International Flat-Rate Envelope',
        'Priority Mail Int Flat Rate Box' => 'Priority Mail International Flat-Rate Box',
        'Priority Mail Int Flat Rate Lrg Box' => 'Priority Mail International Large Flat Rate Box',
        'First Class Mail Int Lrg Env' => 'First Class Mail International Large Envelope',
        'First Class Mail Int Package' => 'First Class Mail International Package',
        'First Class Mail Int Letters' => 'First Class Mail International Letters',
        'First Class Mail Int Flats' => 'First Class Mail International Flats',
        'First Class Mail Int Parcels' => 'First Class Mail International Parcels'
        );

and the module in 1.38a:

$this->intl_types = array(
        'Global Express' => 'Global Express Guaranteed',
        'Global Express Non-Doc Rect' => 'Global Express Guaranteed Non-Document Rectangular',
        'Global Express Non-Doc Non-Rect' => 'Global Express Guaranteed Non-Document Non-Rectangular',
        'Express Mail Int' => 'Express Mail International (EMS)',
        'Express Mail Int Flat Rate Env' => 'Express Mail International (EMS) Flat Rate Envelope',
        'Priority Mail International' => 'Priority Mail International',
        'Priority Mail Int Flat Rate Env' => 'Priority Mail International Flat Rate Envelope',
        'Priority Mail Int Flat Rate Box' => 'Priority Mail International Flat Rate Box',
        'First-Class Mail Int' => 'First-Class Mail International'
         );

As 1.38a supposed to be newer but there is one thing that kept me thinking, the code in the 1.38a module says >>>
* @version $Id: usps.php 7503 2007-11-27 20:36:04Z ajeh $
and the code in the May 2008 patch says >>>
* @version $Id: usps.php 8516 2008-05-13 01:56:07Z drbyte $
which is newer so I was wondering if the patch applied to ALL zen cart versions including 1.38a, or if version 1.38a USPS module was already up to date ...

BTW I am not sure if this affects in any way the problem with shipping estimates I mentioned in the subject.

Thank you
