Sorted article list?

This solution worked for me for products displayed in the archive page…

Under wp-order-cart/templates/products.php, go to ~line 33 where this code is:
<?php if (have_posts()) : while (have_posts()) : the_post();?>

Above that line, add this code:
<?php query_posts($query_string . ‘&orderby=title&order=ASC’); ?>

I have it sorted by title, but you should be able to change it to another field. Also, be aware that this will be overwritten if you update the plug-in.
