You could create a very simple snippet that would simply output the tag value when the key/value pair for tags is present in the query string.
Vary basic snippet (ex snippet name: dyntagtitle):
//-- Get all request string key/value pairs
$s = $_REQUEST;
if($s['key'] == 'tags'){
return $s['tag'];
} else {
return false;
}
Then on the page template simply put the snippet call where you want it to be displayed:
cheers
