Fix/adjust/remove/modify tests that depend on dictionary ordering.

Addresses #741

There may still be more that need fixing since

1) NumPy and some other optional packages do not yet work with Python3.3 so those tests weren't checked

2) Finding these errors by running the tests is nondeterministic itself (e.g. passes 4 times and fails on the 5th).  And inspecting all of the tests by hand is error-prone too.
