Perhaps, there is a misunderstanding here. The score of this node, would (of
course) be win in 100. There is no need to do the losing move. If you mean the
scores of the two positions after those moves - I ghink Guy has given a perfect
answer. Let it phrase it in my words. Assume 256 values from 0-255 you have
available. You can choose to mean:

value meaning
0     draw
1     broken
2     mate in 1
3     mate in 2
...
128   mate in 127
129   mated (in 0)
130   mated in 1
131   mated in 2
...
255   mated in 126

You can also chose other combinations of left and right side of this table.

Dieter
