Oh dear - I knew I would join eventually.
There is danger in actually defining terms when essentially we are talking about PR.
This is not dishonest, it is pragmatic.
The 5 stars are great, because they are so simple that any CEO or CTO thinks they can understand them.
"Get me to 3 stars by yesterday!"
Anything more complex (two scales, etc.) would completely undermine this.
I could argue step for step why each is not exactly right, probably with all the problems already mentioned, but that reminds me of minor (and irrelevant) political parties arguing over the exact meaning of phrases in their favourite book and expecting the world to care, rather than walk on by.

By the way, on the open front:
"Available on the web (whatever format), but with an open licence"
I choose to parse this as the licence being open, not the data.
That is, having a licence that I can examine is the most important thing, the content of the licence is not so relevant.
It does not say
"Available on the web (whatever format), but with an open content licence" or some such.

OKFN open has been mentioned - if you want to see an OKFN view of open, I think
http://blog.okfn.org/2010/10/15/open-licenses-vs-public-licenses/ helps.

So let's just please fix the typos ("hsould be regisetred"!, and is there something missing at the end?) and get on with it - if people want other scales, then that is fine, but don't touch the 5 stars - they really work!

Cheers
Hugh
