Making file-patterns and tag-order work

Hello,

I would like completion to differentiate files according to some
globs. To this end, I've configured:

  zstyle ':completion:*:argument-rest:' file-patterns '
    *(-/):directories:directories
    (*.(ba#k|old)|*~):backup-files:"backup files"
    *.(l#[oa]|py[co]|zwc):compiled-files:"compiled files"
    *.te#mp:temp-files:"temp files"
    .*.sw?:vim-swap-files:"vim swap files"
    %p:globbed-files *:all-files

and also went on to hide all these patterns from the catch-alls in
the last line (is there a way to do this without duplication?):

  zstyle ':completion:*:argument-rest:(all|globbed)-files' ignored-patterns \
  '((*.(ba#k|old)|*~)|*.(l#[oa]|py[co]|zwc)|*.te#mp|.*.sw?|*(-/))'

The relevant options in effect are:
  auto_list no_list_ambiguous auto_menu no_menu_complete
  no_bash_auto_list list_packed

and if I now try completion, I can confirm that these tags seem to
work (indentation added for clarity):

  fishbowl:/tmp/cdt.6kIDed% cat ^D
  directories
    foobar/
  backup files
    foo.bk                     foo.old
  compiled files
    foo.a    foo.la   foo.lo   foo.o    foo.pyc  foo.zwc
  temp files
    foo.tmp
  vim swap files
    .foo.txt.swp
  files
    foobar/      foo.c        foo.txt      g

(you can get the directory contents like this:
  touch foo.a foobar foo.bk foo.c foo.la foo.lo foo.o foo.old \
  foo.pyc foo.tmp foo.txt foo.zwc g .foo.txt.swp
)

I then went on to try to order the tags, because I want e.g. the
swap files to appear last:

  zstyle ':completion:*:argument*' tag-order "
    directories
    globbed-files files all-files
    backup-files
    compiled-files
    temp-files
    vim-swap-files
    "

Unfortunately, this does not work yet, and there are two problems:

1. the directories show up under 'files'. Is this because
   directories are special (they could contain files), or am I doing
   something wrong?

2. There is no change in the ordering. I've tried group-order too,
   but no effect. What am I missing?

Thanks for any inputs!
