I haven't tested this, but if I were to make the change you're looking for, here's where I'd start. In "index.php" look for the following chunck of code:

if($search) {
	$from_where .= $search;
	$order_by = '';
} else {
	$order_by = " ORDER BY link_published_date DESC ";
}

Change "link_published_date" to the value you want to use to sort the stories on your main page. Hope this helps. :)
