It is not necessarily that simple.
At one extreme there are only 3 classes (won, drawn, lost).

But surely a position that wins in 4 more moves is "better"
than one that wins in 30 more moves?
And even among positions that win in 4 more moves
surely some are more aesthetically pleasing than others?
(I prefer the ones where the pieces are in alphabetical order!)

At the other extreme every distinct position has a distinct ranking,
so no two positions are considered equally "good".

Current computer chess play makes the above rather academic, however.
GNUchess does not "know" that it can win with an extra queen,
let alone with a mere bishop.
