Custom post ordering

Is it possible to order all my custom posts in one list? I have 7 custom post types for a blog-system. The client wants to be able to order the posts, which is normal. Problem is that all the plugins I find only let me order the posts per custom post type (like this one for instance: http://wordpress.org/plugins/simple-custom-post-order/)

What I need is something global. Something that takes all my custom post types and put them in one list, so I can arrange them in that way. Would you guys have any idea how to do this, or even better, would any of you know a plugin that does this?

Thanks.
