A sufficiently high score to cause the walk to go through an overriding
node. Although this can be 0, setting it to a positive value has the
desirable side effect that it reduces the competition of "free-floating"
multiple-character phrases. For example, if the user override for reading
"a b c" is "A B c", using the uppercase as the overriding node, now the
standalone c may have to compete with a phrase with reading "bc", which in
some pathological cases may actually cause the shortest path to be A->bc,
especially when A and B use the zero overriding score, as they leave "c"
alone to compete with "bc", and whether the path A-B is favored now solely
depends on that competition. A positive value favors the route A->B, which
gives "c" a better chance.
