NFPA 55 should answer most questions about this. I'm sure there are plenty of CGA publications out there also.
I personally would not reccommend storing cylinders on their sides as, among other reasons, it would defeat one of the purposes of the pressure relief valve should an unexpected release occur. If you take a look at the caps on cylinders (those equipped with caps) you'll notice holes - those holes are spaced in such a fashion as to distribute the cylinder contents evenly in the event of a pressure release thus (hopefully) keeping the cylinder from performing rather interesting gyrations, damage and injuries.
Unless using cylinders that are specifically designed to be stored and even used while on their sides, I would defer to the experts (CGA, etc) who have told us that it's not a good idea for "normal" cylinders to be stored or used this way.

No reason – prevent from rolling; protect from impact.  Did this all the time at oil research centers

Excuse the cross-postings.

Besides not storing acetylene (and other fuel gases) horizontally, can you think of any reason why gas cylinders can’t be stored horizontally?
