By accident I discovered that order seems to matter so I
set up a test like this example to see what what would happen.
After setting up the test, searches were done with different keyword order.
I got the impression from adwords.google.com that order only
matters between double quotes but not within brackets.
But, my ads only showed up when I searched with the keywords
in the same order as entered in one of the ad groups.
Perhaps the order of keywords in a search only results
in a preference for the ad keyword order within brackets.
My conclusion is that brackets work like double quotes!
Has anyone else arrived at this conclusion?
