Profile : Changing order (weight) of profile using the up / down arrows in the selector causes a fatal error

Non-recoverable error is thrown by this operation:

"is not of the type Integer"

Probably should remove the up / down arrow (order) column from this selector since weight is only relevant for profiles Used For "My Account" and "User Registration". We can then expose Weight in the settings form only if the Used For value is one of those.
