On the topic of the zone code: while the country codes are ISO 2-letter and ISO 3-letter, zone codes in Ubercart are all over the place when it comes to length. For example, Australia has a mix of 2- and 3-letter codes:

  $zones = array(
    array(36, 'NSW', 'New South Wales'),
    array(36, 'QLD', 'Queensland'),
    array(36, 'SA', 'South Australia'),
    array(36, 'TAS', 'Tasmania'),
    array(36, 'VIC', 'Victoria'),
    array(36, 'WA', 'Western Australia'),
    array(36, 'NT', 'Northern Territory'),
    array(36, 'ACT', 'Australian Capital Territory'),
  );

From the forum post:

Or it is going to be KL when you consider the Region abbreviations:
Hong Kong Island (HK), Kowloon (KLN), and the New Territories (NT).

We can use KLN for Kowloon, if that's the preferred abbreviation.
