I've seen a major shift in how Google considers links in directories with a reduction of visible PR, at least in some of the directories we subscribe to. PR may have some influence also on TR.
IMO Hub Score was easy to detect and invalidate if the links were irrelevant to the theme of the page, and easy to score upwards where a direct quality relationship occurred.
At this stage, I haven't worked out if the inbound link strength to our sites from directories has effected rankings, but I'm not just talking about directories.
In the past some folks might add a number of outgoing links to high quality and well known pages to increase the hub score of the page . The most wide-spread method for creating a massive number of outgoing links is to be found on directories. Some are more authoratitve than others, and some of course are human edited, suggesting care and effort has gone into the quality control, hence providing a validation for the search engines.
I don't think about a hub score. What you link to, imo, has something to say about what that page is relevant for. That's why sometimes sites that link out to another site start ranking for the name of the product or site they're linking to.
