The W means "Lower bound of Wilson score", which gives higher value to the caches that have more FP than the ones that have only few of them. This should yield older and time-prooven caches in front of the shiny ones that might be gone in year or two.

It is explained in this statistics page:

In very short, in order to get a high Wilson score it is necessary to have both a good FP% and many logs. A cache with two logs and two FP (and thus 100% FP) doesn't cut it.
