Keeping in mind Rocket's answer I prefer to use .index() approach like following:

$.fn.isAfter = function(sel){
    return $(this).index() > $(sel).index();
};
$.fn.isBefore= function(sel){
    return $(this).index() < $(sel).index();
};

It seems more clear for reading/understanding and works perfectly in rows selection.
