Sort a SELECT box's OPTIONs alphabetically

SortSelect.jquery.js - Converted to natural language sorting

var SortSelect = function(select) {
	var options = jQuery.makeArray(select.find('option'));

	var sorted = options.sort(function($a, $b) {
		jQuery(a).text() > jQuery(b).text()
		var a = jQuery($a).text();
		var b = jQuery($b).text();

		var ax = [], bx = [];

		a.replace(/(\d+)|(\D+)/g, function(_, $1, $2) { ax.push([$1 || Infinity, $2 || ""]) });
		b.replace(/(\d+)|(\D+)/g, function(_, $1, $2) { bx.push([$1 || Infinity, $2 || ""]) });

		while(ax.length && bx.length) {
			var an = ax.shift();
			var bn = bx.shift();
			var nn = (an[0] - bn[0]) || an[1].localeCompare(bn[1]);
			if(nn) return nn;
		}

		return ax.length - bx.length;
	});

	select.append(jQuery(sorted))
		.prop('selectedIndex', 0);
