freeoptions to work with "Always Free Shipping"?

[Ajeh]

This IF statement controls when USPS shows ...

    // disable only when entire cart is free shipping
    if (zen_get_shipping_enabled($this->code)) {
      $this->enabled = ((MODULE_SHIPPING_USPS_STATUS == 'True') ? true : false);
    } 

I don't know how well this will work as it is not designed for this if you use:

    // disable only when entire cart is free shipping
//    if (zen_get_shipping_enabled($this->code)) {
      $this->enabled = ((MODULE_SHIPPING_USPS_STATUS == 'True') ? true : false);
//    }
