The location hook sets mkgmap:postcode (if --bounds is used).
The StyledConverter looks for a tag mkgmap:postal_code
So, if I got that right, the style should evaluate mkgmap:postcode and than set mkgmap:postal_code.

It's hard to say. Even if you find the string mkgmap:xxx in the java sources, it is not sure that
this part of  the program will ever be executed.

yes, a lot of normal tags are used when eg. a cycle way is created. I think most of the 
tags listed in hardcoded.tags.txt will be used somewhere. For more details,
one has to search the java sources for the string constant and try to understand what's
happening.
