Perhaps mentioned already... in the layouts where Google is showing organic-sized listings for the 7-pack, it is not showing sites with Place Pages only. Ie, to appear in the organic listings (as opposed to the Map listings), from the results I've seen, anyway, a local business must have a website.
If you search for the business specifically, though, and it doesn't have a website, its Place Page and a small onebox map listing will appear at the top of the organic serp.
Also, in the organic listings, Google is treating Yahoo Local category pages apparently as any other directory, and local.yahoo.com category pages are appearing.
I don't believe that Google has similarly organized its own Place Pages into categories. (You could easily argue, of course, that Google doesn't have to, since each of the 7-pack results does have link to a Place Page that lists related or nearby results).
This might indicate to me that directories with sufficient branding and/or organic authority do have a shot at getting listed in these searches, as long as their local pages look like dedicated pages rather than internal search results.
It's just much too confusing to see one set of map results on the SERPs and another on maps.
I don't see how Google could easily resolve the differences. In the Google Map listings, it's not necessary for local business to have websites... whereas in the organic listings, at least for now, it is.
Also, the map listings currently don't show directory sites. They are brick and mortar (or maildrop) only.
