I never suggested using the play order number alone. But that number should be unique (if the playorder exists in the ncx). If it wasn't, adding 'text' or 'navpoint-' in front of it wouldn't help make it so.
Play orders don't have to be consecutive, but they can't repeat if present. So if they ARE present in your epubs, it should be trivial to create your "prettier" (and still unique) navpoint id from them using regex search and replace.
