Sort Options in a Select List with javascript/jQuery.. but not alphabetically

Question

I am looking for a function that will take a list of options in a select list and sort them alphabetically but with a twist. All values with the text \'NA\' should be pushed to

If you have more than one select in the page (multiple selects) use this:

function NASort(a, b) {
    if (a.innerHTML == 'NA') {
        return 1;
    }
    else if (b.innerHTML == 'NA') {
        return -1;
    }
    return (a.innerHTML > b.innerHTML) ? 1 : -1;
};

$('select').each(function( index ) {
    $(this).find('option').sort(NASort).appendTo($(this));
});
