Maybe this whole mini-sitelinks thing has not yet fully propagated all over. In my area every site who was given mini-sitelinks shows them no matter the search and position.

Or: it could be just a trial of some sort. I have not seen the big "hooray" Goolge usually makes with something like this. Remember the big PR campaign they pulled out when the original sitelinks were implemented? I am yet to see Google mentioning this at all.
