Could it be 1276? (Score 1)

I think the S in the code is to be replaced by the location of the extra S in basse. The extra S is the 20th character in the phrase, and if you look at the hex/symbol pairs, the 20th character is a 4. That leaves you with 4FC in hex which translates to 1276. Of course this seems too simple so it's probably wrong, but I thought it might spawn an idea or two about how to tie in the significance of the extra S to the symbols at any rate...
