It's just the LVs don't have partition table stored anymore: You probably got the device order partially correct, which would put some of your data blocks in the correct location. Having the LVM metadata line up is not terribly surprising. When some drives are placed back into the correct slots, but not others, only the non-parity data on the correctly placed drives will be correct. The rebuild will destroy the parity data on those devices, and much of the data on the other devices. Your partition tables were probably among the latter. If chunk size, data offset, or layout were also incorrect, then even fewer good data blocks will show up by chance in the correct location. Without the original mdadm -E reports (complete), there's no way I know of to figure out what happened, much less repair it.
