Proposed resolution (July, 2009):

Change [expr.static.cast] paragraph 9 as follows:

A value of a scoped enumeration type (9.7.1 [dcl.enum]) can be explicitly converted to an integral type. The value is unchanged if the original value can be represented by the specified type. Otherwise, the resulting value is unspecified. A value of a scoped enumeration type can also be explicitly converted to a floating point type; the result is the same as that of converting from the original value to the floating point type.

The current wording of [expr.static.cast] paragraph 9 does not permit conversion of a value of a scoped enumeration type to a floating point type. This was presumably an oversight during the specification of scoped enumerations and should be rectified.
