If you type <ctrl+x><h> at the point where you're hammering TAB, you'll 
get some debugging information that could be useful.

I assume this was mangled by mailing (extra newlines)?  But, even that line when 
demangled, along with this other line you listed:

> zstyle ':completion:*' file-sort access

causes the problems you describe.  I have no idea what that matcher-list 
is trying to do, but this is a full, reproducible test-case for me:

==> badzshrc <==
zstyle ':completion:*' file-sort access
zstyle ':completion:*' matcher-list '' 'l:|=* r:|=*' 'r:|[._-]=** r:|=**' 'm:{[:lower:][:upper:]}={[:upper:][:lower:]}'
autoload -Uz compinit
compinit
================

$ zsh -f
$ . ./badzshrc
$ tar xvf [Tab]

At that point, ^xh produces:

tags in context :completion::complete:tar::
     globbed-files  (_files _tar_archive _tar (eval))

Whereas the working case produces:

tags in context :completion::complete:tar::
     globbed-files  (_files _tar_archive _tar (eval))
     directories    (_files _tar_archive _tar (eval))
     all-files      (_files _tar_archive _tar (eval))
