I thought running bond was better than stacked bond since there is no interlock of the block and that is why you need reinforcement more often.

Are you using running bond? If that's the case, yes. If you use stack bond, it's min 24". Running bonds are not as reliable.

Subject: CMU wall reinforcing

I have a pair of short special reinforced CMU walls that are being 
designed under SDC D.  Based on the masonry code (TMS 402-08), the 
vertical and horizontal spacing has to be less than the wall length/3 
(1.17.3.2.6).  For a wall 2'-8" long, I come up with a spacing of 10.7" 
oc, i.e. every cell.  Am I interpreting this correctly.  There is 
minimal shear and for out of plane loading, the verts can be at 24" oc.
