It's a little odd to mention Tiger/Line and optimized for geocoding in the same sentence. Tiger/Line is specifically obscured to protect the anonymity of individuals that live in low density areas. It's de-optimized for geocoding before it is published for public access. It seems pretty likely that's the issue above.

Of course OSM is not a great source of addresses either, as it simply doesn't have data for so many regions.
