Normally tunings are listed from low to high, not high to low (which I assume you did).

This tuning would come from tuning a guitar to Bb standard, and then lowering the lowest two strings a whole tone each. I don't think its that weird of a tuning for a six string, provided you have sufficiently heavy strings.
