Oh, it does:

strings /usr/bin/sort |grep tmp
/tmp

man sort:
       [...]
       If the environment variable TMPDIR is set, sort uses it as
       the  directory  in which to put temporary files instead of
       the default, /tmp.
       [...]

gnu/usr.bin/sort.c:
  [...]
  temp_file_prefix = getenv ("TMPDIR");
  if (temp_file_prefix == NULL)
    temp_file_prefix = "/tmp";
  [...]

Around ~16GB on one system (one of them that pukes about too small
/var/tmp when running weekly).

Wich is about average I guess.

I think I'm "Joe Average Common User" :-)

Ok, go and change sort&co. now and upset other people...

All NetBSD tools should show the same behaviour IMHO.
