I think it's a bit much having 101 return codes to reflect the score

Parsing the "-v" output would work.  Even simpler is the output of terse 
mode, i.e. "-vt", which defaults to

N 0.000000
Y 1.000000

There's a config file option named "terse_format" that allows changing the 
format of the above lines.  The format above (which is "%1.1c %f") could be 
changed to "%4.2f" so values would print as 0.00, 0.93, etc.
