 I'm finding it incredibly difficult to sort a post type using the existing
 filters to order by custom post meta alphabetically on a single post (for
 next/previous post).

 A use case is when I have a separate field for a custom post type called
 "Last Name" where I would want my posts to display in alphabetical order
 by last name. When sorting on an archive with pre_get_posts, it's not a
 problem, however when navigating posts from the single post, there just
 doesn't appear to be a simple way to change the "next" and "previous"
 posts to maintain the same custom sort order when dealing with an
 alphabetical meta_value.

 I'm proposing adding one or two filters to the get_adjacent_post()
 function which allows the final query to be filtered, or more importantly,
 the query result to be filtered so a custom sort can be implemented.
