One interpretation is that it might be a glitch in the updating of multiple databases.
Another is that widgetsarefun.tld has such weak backlinks, or is so infrequently searched, or both... that Google might assume it's simply not of interest and might even be a kind of typo in relation to this particular query.
What you describe reminds me of the very agressive spelling correction we had around the launch of the MayDay algorithm... where if a phrase spelling was statistically weak enough (ie, infrequently occurring or infrequently searched, or both) in comparison to a frequently-used word combination, Google would identify it as a probable typo.
What you're seeing might be a similar example of how Google is treating searches that are statistically overwhelmed by something similar... using a different serp ordering for disambiguation (instead of a "did you mean" flag). See my comments in several posts on this thread...

This could well be an analogous situation. How long has this been happening?
PS: To expand on Sand's question, which I see as I'm posting, I'm thinking this might relate either to the age of the site, or perhaps to the particular type of indexing that Google might be rolling out with the Everflux Panda style of updates. (I have no precise thoughts about what this might be, but, if this is a recent observation, then something in my gut says there's a relationship).
