They are sorted, first, according to the text of the label (ie the text 
of the zip code itself), and then by the map number (for entries that 
have the same zip).

They don't appear to be sorted within the map tile LBL section that 
could be a problem -- everything else in that section is sorted.

I agree, I think the fact that you are not given the option to search on 
zips means that it is not going to work. If sorting were the problem you 
would have the option, but the search would often fail. That has been 
the experience everywhere else anyway.
