Probably too late, but this plugin only changes the order in the admin area.
You must write your own queries on the front-end. So there’s some code required on your end. It’s pretty much how most of the decent reordering plugins work, although there are a few free/paid that do the front-end work for you, but I strongly recommend not using these because the code to do it is rather trivial when you get around to it.
We have docs set up here that have some examples on how to reorder on the front-end.
