There are photos of both O. pubescens & O. tomentosa in "The Cactus Family" book. The tubercles, pad shape and plant height all match the photo of O. tomentosa in my book. The photo in the book of O. pubescens looks nothing like your photos because the stem segments of O. pubescens are lighter green, and they are cylindrical (not flattened and oblong).
O. pubescens only grows to 31 inches high, the one in your pict looks to be far past that height.

heres a photo of tomentosa,

As far as the label goes, well I seen some plants in other Botanical Gardens and places that have accidentaly been labeled wrong also.

I've also attached a photo of my tomentosa.
