Wordpress - list posts by modified date

Question

Hi,

How do I list my posts in Wordpress ordered by modified date instead of created date?

I have it as
<?php $posts=query_posts($query_string . '&orderby=post_modified&order=ASC'); ?>
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>

Having orderby=title does sort the posts by title but my above query doesn't work.
Looks like orderby=post_modified isn't recognized.

Thanks,
Tee

Ah ok... I figured it out.
orderby=post_modified needs to be orderby=modified.
