Coda Wheel and Sign not printing

[Tim Sawyer]

Hi,

I'm using Lilypond 2.0.3 to write some drum music.  I've just upgraded from 
1.8.2 to 2.0.3, and my coda wheel and sign now both appear as a number 1.  
These worked under 1.8.2.

Here's how I'm using the signs:

e4. e8 e8 e8 e4 e8 e4 e8 e8 e8 e8 e8 e8 e8 e4. r4. \mark #'(music 
"scripts-segno") \bar "||" e8 e8 e8 e8 e8 e8 e4. e4. e8 e8 e8 e8 e8 e8 e4. 
r4. \mark #'(music "scripts-coda") \bar "||"  e8^"To Coda" e8 e8 e4 e8 e8 e8 
e8 e4 e8 e4 e8 e8 e8 e8 e4. r4.^"D.S. al Coda" \bar "|."

Can anyone suggest where I can look to try and resolve this?

Cheers,

Tim.
