Command lines sound easier compared to functions for a non-programmer 
like me.

My opinion (which mostly doesn't count) being that since most 3rd party 
engines would either use a yes/no combination OR a number OR a %age, the 
generic plugin ought to use a generic input method. Though that could 
complicate matters and code exponentially.

Situation one (as already proposed by Julian)
=============
The 3rd party engine outputs SPAM / NOTSPAM, in which case use the 
following flags
a. NO (surely not spam)
b. YES (surely spam)
c. SKIPPED (if no output is found)

Situation two
=============
The 3rd party engine outputs a %age or a number (say -100 to +100) then 
the input filter will watch for a number and based on that give the 
following flag
a. NO (surely not spam)
b. MOSTLY_NO (mostly not spam)
c. MOSTLY_YES (probably spam)
d. YES (surely spam)
e. SKIPPED (if no number is found)

Flag Action: (again as recommended by Julian)
The above flags NO,(MOSTLY_NO),(MOSTLY_YES),YES,SKIPPED with a 
configurable score in MailScanner.conf seem most flexible to me.
