Php/mysql Database Order Problem 2

I would like to order the list below, but it does not follow any numeric or alphabetical order. There however is an order to the individual letters, which is as below:

M=0
D=1
Vd=2
Ms=3
S=4
Hs=5
Mvs=6
Vs=7

The letters are stored in the database. Is there a way to order these using sql without changing the data stored in the database?

Also in #PHP _↴
