This makes the scoped property system mimic the behavior of CSS. When there is a tie, the scoped properties loaded later in the cascade win. I also optimize the scanning of all the properties, checking only those sets of properties that have a value for the desired key path, to reduce the need to match a ton of scope selectors.
