Order of the Signs

Hello,
I know the order of the signs also relate somewhat to the locations on our body. However, is there more to the order of the signs?

In mythology they are related to-among other things-the 12 Labors of Hercules' in esoteric astrology there are several connections with the order of the signs; see, for example, M. P. Hall's "Astrological Keywords" for one of the meanings regarding the signs and their order.
