OpenSUSE 12.3 is using kernel 3.7 which is also old for this sort of recovery attempt. Even openSUSE 13.1 is at 3.11.6 which might work in a bind, but if it doesn't, inevitably someone will suggest you use something even newer. Current stable is 3.14.1, I suggest giving 3.13 or 3.14 a shot at this with -o ro,recovery as a first step and see if it at least mounts. And an old kernel implies old btrfs-progs too, which is where the code for btrfsck and btrfs restore is contained. So that needs to be at least v 3.12. And hopefully you didn't use --repair with btrfsck yet.
