I recently purchased the 2013 edition but last used the 2011. I noticed A LOT of the first few orgo questions in the 2013 edition were exactly the same as those from the 2011 edition. It all comes down to concepts though.

The new version has everything that the old version had, plus new questions in every section. If there is not too much financial difference, get the new one.
If I were you I'll invest on 2013 edition. It's a known fact that Orgoman update their book every year and with every new edition there are more questions added.
good luck
