[wp-hackers] How to change the sorting order by of a custom post type's rss feed?

[Bjorn Wijers]

Hi,

I've been trying to setup a (rss) feed for my custom post type.
This works using the url parameter post_type.

For example:
http://wordpress.com/feed/?post_type=my_custom_post_type

However I would like to change the sorting of the custom posts based on 
a meta key and value.

I expected something like this:
http://wordpress.com/feed/?post_type=my_custom_post_type&order_by=meta_key

Can somebody point me in the right direction on how to achieve this?

Thanks in advance!
