And I've noticed something similar in PS - with some images, lowering the
quality slider will sometimes produce larger jpeg files. I remember reading
why this occurs but have since forgotten.

Subject: jpg oddity
I was wondering how LR would be able to handle the RAW to jpg conversion on
my Chaos image for the PUG. As I suspected, the chaotic image did not
compress as readily as my usual shots, and I had to bring down the 0-100
quality slider in LR. As I went through a series of trial-and-error
settings, I was very surprised to find a discontinuity of sorts.
At a quality setting of 70, the file was 305mb as reported by my iMac OS-X
10.7.5.
At a quality setting of 69 the file size dropped all the way to 264mb.
By comparison, I usually use a quality rating of 82-89 to compress one of
my RAW images to a 300mb PUG submission.
