I didn't take any particular action over the stairs. I did my usual workflow when presented with "these images won't stitch - I've tried everything". In brief:
I load in the images and input all the information I have about the project on the Lens Details and Image parameters tab. I set the image parameters (y,p,r) to their nominal known positions - either manually (using fill yaw etc) or by applying a template or Align to Grid. I then generate control points from the Control Points menu only between horizontally and vertically adjacent pairs of images. Optimize. Then depending on the result I do whatever seems necessary to get rid of bad points, assign additional points to fill areas where there aren't any (making use of the Generate control points here feature, now that the images are reasonably aligned).
If things initially go awry, I will optimize first the horizontal row (by checking only those images on the Use control points of list on the Create Panorama tab). When those are optimized ok, further images or groups of images can be successively included until all are used.
