Paraplegic here, can confirm (for myself anyway). After reading several discussions/polls online on the subject, it seems to me that the general order of importance is:

1. Resolution of neuropathic pain 2. Use of hands 3. Sexual function 4. Bladder and bowel function 5. (a few other things) 6. The ability to walk

I should note that the discussions/polls I've read are mostly from the United States. The U.S. is probably the most accessible country in the world, and as a citizen I don't miss walking so much because I can still do almost anywhere I want to. If the discussion was among people from undeveloped countries, the ability to walk might score much higher.
