That's a pretty old thread, and geocoding has changed considerably with 10.3 and beyond. That said, I'm not getting anywhere with the locator you provided or even with the out of the box locator; yours returns no results for me (although I may have set it up incorrectly), and the ESRI locator matches them all but neglects to recognize my Unit number field.
My address table has two fields: Address & Unit. When I get my results back none of them are 100%, but rather 93%. I've always been skeptical of geocoding with unit numbers so I've never used them. Sorry I'm not help here; you may want to get tech support on the line and see if they can help.
That should just about do it....
