I don't think it's doing quite what you say (although you don't see what
options you have set), but I agree it won't do what you expect...

If the arguments are `5' and `access' I would expect the words to be
divided as:

man 5

(which is certainly what I get with my option settings).  The problem is
that the argument to -t is being divided into two parts.  To prevent that
you need:

man() {
    screen -h 0 -t "man $*" man $@

Actually, that last argument could be $* as well; if you want to
maintain zero-length arguments it needs to be "$@".
