Your 24-70L is clearly defective, or misfocused in these tests. My old 24-70L was far sharper at f/2.8, and yours isn't sharp by f/5.6 in the posted pictures. The TS looks like a winner (and of course the 14-24 is no slouch).
EDIT: Even this doesn't look as good as my copy did, but still obviously better than the photos posted in the test here: http://tinyurl.com/madlso
A missfocus is highly unlikely with liveview at 10x magnification. It could be that the sensor-plane was not exact parallel to the wall. But if this was the case then each of the three lenses should suffer under this uncontrolled parameter in the same way, because the focus-point was the same for each lense.
It could be that my 24-70 is defective, but this is in my mind also pretty unlikely. I tested my 24-70 against another 24-70 from a friend. His lens had better contrast, but the sharpness was nearly the same. I also tested my 24-70 against my 16-35 (Mark I). My 24-70 was better at all apertures at the whole range 24-35 (after this test I sold my 16-35). And, as I allready wrote, Canon has tested this lens a few weeks ago and I have a writen statement from Canon, that the sharpness of this lens was tested is within spec.
Best regards,

i'm not the tiniest bit surprised the 24-70 would look like that in the corners, I am a little surprised it would be like that in the center though
i have found that sharpness tests are insanely, ridiculously sensitive to focusing variation and even using 10x zoom LV I need to give it at least 3 separate goes to really start feeling good about the fairness of a comparison.
