The main description says:
This is a simple plugin that enables users to modify the order in which posts are displayed on all pages(or in selected categories) of the blog.
But, after installing, the description says:
Please note: once the order has been set, the post display order will be the same anywhere in the blog; the current version does not support different display orders for different categories/pages within your blog.
Once of these is a lie, but I'm not sure which, because clicking on the tab under tools to set the order brings up an error message. Plugin does not work in 2.7.
