well you need to make sure what ever mirc you are runing this on that you have access to give chan lvl's...

you can just do

on *:text:.Add*:#: { 
  if ($nick != $3 && $nick isop # && $me isop # && $3 ison # && $2 isnum 3-10) { 
    .cs access # add $3 $2 
    .notice $3 You Just Got Access to # at lvl $2 from $nick 
  }  
}

oh and
