This is similar to How can I change the order of address field columns on screens and reports?, but relates to the order the fields are show when "pay later" information is requested.
I would like to move the "Postnummer" (post code) to before the "Postadress" (City), because that's the way we do it in many European countries ;-)
And I would like to avoid hacks like the one suggested in How to change order in billing address.
