From http://xprize.com/teams/guidelines.html :
6. Entrants must specify and provide the ANSARI X PRIZE Rules
Committee with their take-off and landing location, and the date of
their launch, not less than 30 days prior to any flight attempt.

So, unless the X-Prize commitee has kept the notification secret, they
don't meet the requirements.

Also, the press release does not mention whether or not ballast will
be carried as required by the rules.

Also, the press release states that "Based on the success of the June
space flight attempt, SpaceShipOne will later compete for the Ansari X
Prize,", leading me to conclude that this flight is not part of the
competition.

That settles it then, it's not an X-Prize flight. My
mistake.
