Raster3D (specifically the label3d script) uses Ghostscript to process
labels, and can thus handle any PostScript font including Symbol.

If I understand your problem correctly, the underlying cause is that 
Molscript is not passing the label+font information to Raster3D in the 
first place. Instead it converts the individual characters to vectors and
passes the vectors to Raster3D.  This could be fixed by hacking 
Molscript to simply pass the coords+font+label directly as a set of 
Raster3D input records.  If I get some time (hah!) I'll take a look at it.
Or I would be happy to provide guidance on the correct Raster3D 
input syntax if someone wants to tackle it.
