Write a function (say, score_contains) that returns NULL whenever
contains would return false, and the score otherwise.
SELECT * FROM (
SELECT *, score_contains(mytable.title, 'Winding Road', 1) AS
score FROM m

I don't know what ANSI says, nor do I know what PostgreSQL exactly does
at the moment, but, the only thing you can reasonably count

Is there a knowable order in which functions are called within a query in
PostgreSQL?
For example I'll use the Oracle "contains" function, though this is not
exactly what I'm doing, it just illustrates the issue clearly.
select *, score(1) from mytable where contains(mytable.title, 'Winding
Road'
