[wp-hackers] Global meta_key ordering for a custom post type

I'm writing a plugin that enables a custom post type for WP3. The post type is
for tasks, so I use a meta_key "priority" that I would like to sort the posts by.
Doing the widget is a snap, I'm using:
$r = new WP_Query(
'post_type' => 'custom_task_type',
'post_status' => 'publish',
'meta_key' => 'priority',
'orderby' => 'meta_value',
'order' => 'DESC',
'meta_compare' => '>=',
'meta_value' => 5,
... to sort the posts for the widget using the "priority" meta_key's value and
only accounting for posts with a "priority" meta_value greater than 5.
*But*... for general post ordering in archive (I also have custom taxonomies)
and single page mode (that would also influence things like get_next_post()),
I'd like to be able to influence the global loop ordering, using the priority
meta_key, for *any* query that involves my custom post type.
Basically, my custom post type should never be ordered by post date, under any
circumstances - always by using the meta_key's value, otherwise the ordering
would simply not make any sense.
What is the best hook to use in my plugin, to influence the ordering of any
query that *involves* my custom post type? Should I go the query_posts() route?
A simple example would mean the world to me at this point.
Thanks for your time and effort if you have read this far :)
