> Normally, lilypond returns value 0.0 if a numeric property isn't set

No, it doesn't.  LilyPond returns SCM_EOL (the Scheme empty list  
constant, '()) for unset properties, regardless of the property's type.   
Only if you use robustscm2number on that or whatever it is called do you  
get whatever you specify as second argument.

The usual way, for that reason, is to use scm_is_number on the result of  
the property getting call and consider the property unset if it is not a  
number.
