display: none (which is what jQuery's hide() function does to matched elements) will not work for option elements in a reliable, cross-browser manner. Instead, you need to remove them from the DOM, and then add them back in after the search.

This is a little tricky, as you need to store the original order. I'd be tempted to just delete non-matches, and then restore. Something like this:

var clients = new Array();
clients[2] ='aa';
clients[3] ='bb';
clients[4] ='cc';
clients[5] ='dd';
var restore;

function search(val) {
    $('#cl_sel_l').html(restore);
    for ( var i in clients) {
        if (clients[i].toLowerCase().search(val.toLowerCase()) == -1) {
            $("#c_" + i).remove();
        }
    }
}

$(function() { restore = $('#cl_sel_l').html(); });
