[Plugin: Archivist – Custom Archive Templates] Order by

Hi
Figuring out how to make this work on my site, however, there is one thing that I’m stuck with.
To order the results, I’m using the plugin to display a category of pages, I was hoping to use something like order_posts_by="menu_order", which I’m using for a custom post type, and thought I could change ‘posts’ to ‘pages’.
No luck there, do you have an idea how this might be possible?

Regards
Thorir
