Uh, it does *not* happen, I just checked it.  I know that
/var/cache/fonts/{pk,source,tfm} are included in the deb, with owner set
to root and permissions 4777.  I do not know why after reinstalling the
package the permissions are not reset by dpkg to the values in the deb.
I also doubt whether this is on purpose, or a bug in dpkg, or whether
there's actually some clever mechanism I forgot in our package that does
the trick.  Note that I tested without apt-utils installed, so the
config script is run after unpacking.

Yes, for all subdirectories of /var/cache/fonts.

Yes, but it would also only be needed for them - for the others there's
no possibility of dpkg overriding user's changes.
