Custom Ordering

So I am working on creating a plugin that adds staff members. I want to be able to customize the ordering, instead of just alphabetically.
I have a custom post type for saving the order #, but it doesn’t actually put anything in order. Here is what I have so far.

<?php query_posts( array(
 	'post_type' => 'employees',
 	'posts_per_page' => -1,
 	'orderby' => 'dispord',
 	'order' => 'ASC'
)
); ?>

Right now it only sorts by the ascending, but not to the number I assign it to. Any suggestions?
