uups, should be

\uput[-90](B|0,0){\footnotesize 100}

but causes no error in this case ... :-)

(<coor1>|<coor2>): from the first pair of coordinates
take the x value and from the second one the y value. In
the above example it is the x value from the node B and
the y value from the coordinates 0,0
This makes it easy to draw without really knowing
the value of the coordinates.

documented in the docs ...
