I see that the answer is given in the newsletter (July 2012). The answer is that as it is not in the list on the website it doesn't count but that we can request a modification for the climb: we can apply for an additional side. I think in this case that's justified.
FYI: I decided to take the Mazzo route. I made it in 1 hour 38 minutes. And to be honest I enjoyed it; the 26/30 was a succes!
