He's skeptical of the new discovery (properly so, I might add; I'm very skeptical about anything I haven't seen in black and white in a journal, though Lenski is a good scientist), not of the work itself.
If Behe is skeptical of the 'new discovery', it seems to be rather obvious that he is skeptical of the work.
I would say that Behe is an excellent scientist, who also has a firm grasp of the principles of logic.
