Reply To: Other results at top but should be at bottom.

Well, not via settings, but could be doable via a custom code.

add_filter('asp_result_groups', 'add_asp_result_groups', 10, 1);
function add_asp_result_groups($groups) {
	if ( isset($groups['_other_res']) ) {
		$or = $groups['_other_res'];
		unset($groups['_other_res']);
		return array_merge($groups, array('_other_res' => $or));
	}
	return $groups;
}

Try adding this code to the functions.php file in your theme/child theme directory – make sure to have a full server back-up first for safety. For more details you can check the safe coding guidelines.
