terms panel shows top terms based on *alphabetical* sorting of counts

[pheaver]

The counts in the terms panel are correctly sorted when they are displayed. However, when determining the top terms to display in the panel, the top N terms are chosen based on counts that are sorted alphabetically.

For example, if the counts of your top 10 terms are this:

120, 100, 90, 80, 70, 60, 50, 40, 20, 10

And if you create a terms panel with length 5, then you'll get these:

90, 80, 70, 60, 50

But if you create a terms panel with lenth 10, you'll get these:

120, 100, 90, 80, 70, 60, 50, 40, 20, 10

Hmm, yes, I am able to replicate this. Investigating. Test case: https://gist.github.com/rashidkpc/6110289

Scratch that, known issue with Elasticsearch elastic/elasticsearch#1305
