GeoMashup::list_located_posts – list order?

Is there a way to have <?php echo GeoMashup::list_located_posts(); ?> list posts in a certain order? IE by date, ascending, etc?

If not, does anyone know how items are listed? IE are they listed by geo coord. or date that geo data was attached to the post, etc?

Thanks!
