Sort 1 Column to match another
 

I would like to sort column B to match column A like this:

Column A (stays the same) Column B (sorts to match Column A based on
C__)
---------------------------------------------------------------------------------------
Duette\CPLP C20 (34) Duette\C21 (c)
Duette\CPLP C21 (34) Duette\C23 (a)
Duette\CPLP C23 (34) Duette\C20 (b)

The other variable is that the information in column B will have one common
denominator and that is the "C20, C21, C22" the rest of the info may not
match.

Do I need to first isolate the "C20, C21, C22" if I want this to work?
