I'm not seeing any difference in behaviour between 1.2 and 1.3.
As srsa_4c pointed out the code has not been updated to handle the date based folder names Canon now uses; but this affects 1.2 as much as 1.3.

Humm, I think I understand what's going on.
On v1.2, when I activated raw saving, it would create a specific folder for that, and I'm not 100% sure, but I think its naming format was something like srsa_4c mentioned.
On v1.3, there are three alternatives regarding the raw folder: withJPG, A/DCIM and A/RAW.
I tested the three of them and, regardless the alternative, the raws end up on a subfolder like 133___12 (so, depending on the option chosen on the Raw Menu, it would end up like A/DCIM/133___12, A/RAW/133___12, etc.
So, the issue (in A3100 case) seems to be the raw saving functionality, rather then the purge raw.
What do you think?
UPDATE: The fact is (and this I'm 110% sure): with v1.2 I had absolutely no issue purging raws in mass deletion mode.
UPDATE2: I have created a post in the bug thread as srsa_4c told, but since this discussion is evolving here, I will delete it from there.
