Subject: why won't this function work?

Hi all.

I'm trying to convert a function I wrote in bash to zsh.  How can I get this to work?

selhist () 
{
     TAB='       ';
     (( " $# < 1 " )) && {
         echo "Usage: selhist [command]";
         return 1
     };
     oldIFS=$IFS;
     IFS='
';
     cmd=("" `grep -w $1 $HISTFILE | sort | uniq | pr -tn` "");
     IFS=$oldIFS;
     printf "%s\n" "${cmd[@]}" | less -F;
     echo -n "enter number of desired command [1 - $(( ${#cmd[@]} - 2 ))]: ";
     read answer;
     eval "${cmd[$answer]#*$TAB}"
}

Thanks,
GJ
