Rage Mechanics Question and Idea

The game has 1 bit per rage, on $20 bytes. The menu just read those 32 bytes in order. This is how the game add a rage when it's learned in battle:

Code:

C2/4A10: BD 01 20     LDA $2001,X    (Low byte of monster #)
C2/4A13: 20 17 52     JSR $5217      (X = monster # DIV 8, A = 2^(monster # MOD 8))
C2/4A16: 1D 2C 1D     ORA $1D2C,X
C2/4A19: 9D 2C 1D     STA $1D2C,X    (Add rage to list of known ones)

Okay, then how do I change the order of those bytes?
