There appears to be only a loose correlation between McCabe complexity and "excessive complexity." It's not clear how the author converts from one to the other. One would hope that the difference in ordering comes from accounting for the amount of functionality in each project (and even if you prefer bottle to django, you have to admit that django builds in more functionality.) But, again, it's unclear how that conversion happened. I'm wondering if the author ranked "excessive complexity" however he wanted, and the McCabe complexity is just there to give this the veneer of scientific authenticity.
