orderby title does nothing once filtered by date

Hi all,

I’m trying to create a custom feed which grabs the days posts and then puts them all in alphabetical order. I can get them in alphabetical order or I can get all the days posts. However once I filter by date and then try to order them by title nothing happens.

The code I’m using is here:

<?php
$current_date = getdate();
$args = array(
	'posts_per_page'   	=> 90,
	'year'     			=> $current_date["year"],
	'monthnum' 		=> $current_date["mon"],
	'day'				=> $current_date["mday"],
	'orderby' 			=> 'title',
	'order'    			=> 'ASC'

);
query_posts( $args );
include('wp-includes/feed-rss2.php');
?>

You can see a sample of the feed here:

Any help would be much appreciated.

Thanks
