Question about Churchkey's cellar program

Every time I wander into CK I check out the (great) collection of bottles on the wall opposite the end of the bar. Anyone know if these are available to order, or are they put away for special events? I've never seen any of them on the so-called "reserve" list, so I'm curious. I was going to ask yesterday but the Hopslam-coveting masses made it difficult to talk to a bartender for any length of time.
