custom_sort_order
-----------------

   Type: string
   Default: (unset)

   If custom sorting is enabled by setting sorting_method to 12, this
   variable defines the sort order you want to use. It is a
   comma-separated list of the following keywords:

  author      Sort alphabetically (A-z) by realname
  date        Sort by date, oldest first
  highscore   Sort high scoring articles, those without high scores first
  id          Sort alphabetically (A-z) by Message-Id
  lines       Sort by number of article lines, lowest number first
  number      Sort by server number, lowest first
  score       Sort by score, lower numbers first
  subject     Sort alphabetically (a-z) by subject, ignoring case

   As you can see, all keywords use an ascending sort order by default.
   You can however capitalize each keyword to reverse its order (i.e.
   Highscore would sort high scoring articles first, which is usually
   what you expect).

   When comparing two articles, slrn steps through this list, starting
   with the first keyword, until it finds an entry for which the articles
   differ.

   There is no performance penalty when using custom sorting. Actually,
   the other sorting methods are merely there for convenience and use the
   same algorithm internally. As an example, here is a list of those
   settings for custom_sort_order that are equivalent to the sorting
   methods:

 0 and  1  ""
 2 and  3  "Highscore,subject"
 4 and  5  "Score"
 6 and  7  "Score,subject"
 8 and  9  "Highscore,Date"
10 and 11  "Highscore,date"
