Oh, I see. Could I then also change the regex to save two more characters? 
perl -e'sub c{pop=~/.\s/;(ord$&&7).1e3+$`}print sort{c($b)<=>c$a}`du -
+h`'

74 characters.

And, in fact, since we are only using .1e3 to make sure the sizes sort properly, why not save one more: 
perl -e'sub c{pop=~/.\s/;(ord$&&7)**7+$`}print sort{c($b)<=>c$a}`du -h
+`'

73 characters.

In reply to Re^4: du -h, sorted by bellaire
