Particularly when racking from primary to secondary and then again into the keg.
I agree with the comments in Jack Smiths post, however, I'll offer this answer to the Original Posters question.
If you have the "racking from" and the "racking to" vessels protected from light during the racking process, the short time the beer spends flowing through the tubing should produce a miniscule amount of skunk and be undetectable.
The amount of UV from CFLs is fairly mild and shouldn't harm the beer during the "quick" passage vessel to vessel.
While the other post referenced in JackSmiths answer links to a great info about the speed of skunking; and scientific data regarding the speed at which CFLs can cause skunking has yet to bubble to the surface of the homebrewing community/knowledge base.
