Try (in local/config.php):

  $CondTextPattern =   
    "/ \\(:if (\d*|[A-Z]) (?:end)? \\b[^\n]*?:\\)
       .*?
       (?: \\(: (?:if\\1|if\\1end) \\s* :\\)
       |   (?=\\(:(?:if\\1|if\\1end)\\b[^\n]*?:\\) | $)
       )
     /seix";

This allows either a sequence of digits or an uppercase letter to work
as an (:if:) identifier.
