Yes, yes, see the order=Director in the pagelist
below.

This is either a bug or I have the syntax wrong (bad
documentation?), what version of pmwiki are you
running?  Are you saying that the ordering doesn't
work, or the template is bad (have you tried the
ordering with a simple format?)

No, no that would seem really difficult and strange to
implement, :)


And, I found this in the release notes:

  # The (:pagelist:) command can now filter pages 
  based on the contents of page variables and/or 
  page text variables. For example, the following 
  directive displays only those pages that have an 
  "Xyz" page text variable with "some value":
  
  (:pagelist $:Xyz="some value":)
  

This means that you should be able to pre-filter 
your pagelist like this:

 (:pagelist group=Members $:Director=John
 fmt=#memberperdirector:)

and then make your pagelist easier and more effificent
(no need to filter out other directors in the
template, not need to sort the pagelist),

Also, the ReleaseNotes don't seem to mention anything
about being able to sort based on PageTextVariables,
strange,
