The easiest way to set custom priorities is to do so in the buffer. You
could simply add the following line to the top of the relevant file:

--8<---------------cut here---------------start------------->8---
--8<---------------cut here---------------end--------------->8---

This line sets 1 as the highest priority, 5 as the lowest priority, and
3 as the default priority.

Then, once you have added priorities such as the following...

--8<---------------cut here---------------start------------->8---
* A list
** [#5] Some item
** [#4] Another item
** [#2] Yet another item
--8<---------------cut here---------------end--------------->8---

...you can sort them by calling org-sort (C-c ^ p) on the heading. (C-c ^
P will sort them in reverse order.)

The other option here would be to create a "ranking" property for each
item with predefined entry options. You would still be able to sort the
list, but you could also view it as columns and capture it in a table
using dynamic blocks. (Of course, you could also display the priorities
above in column view.)

--8<---------------cut here---------------start------------->8---

* Some item
  :RANKING:  3
* Another item
  :RANKING:  1
* Yet another item
  :RANKING:  5
--8<---------------cut here---------------end--------------->8---
