"case" doesn't loop by itself, you need to call it inside one.  Also
in zsh you probably want to use an array rather word splitting.
Something like

    local -a LS_ARG
    while [[ $# -gt 0 && "$1" = -* ]]
    do case "$1" in
       -j) LS_ARG=(-t -r $LS_ARG);;
       -z) LS_ARG=(-R -t $LS_ARG);;
       *) LS_ARG=($LS_ARG $1);;
       esac
       shift
    done

    /bin/ls -l $LS_ARG $@

However, you might want to look at the "getopts" builtin if you want
to write this in a POSIX-portable way, or at the "zparseopts" builtin
for a zsh-specific alternative.
