The model here isn't flexible enough for what I need. Basically, this allows you to manually create a single sort order for each post type in your system.
This creates a bunch of problems:
For some categories of posts this would be useful. For others, I want to keep the default date ordering. As far as I can tell, this plugin forces you to sort all categories within a post type, or none.
Also, you can't filter your view of posts while sorting them. Since I have several hundred it makes using this problematic.
