If you have a client system that is incorrectly reporting it’s Software Updates scan state, you can use the follow script to force the client to do a full report of the compliance scan state. It has worked for me thus far!
' Script from http://msdn.microsoft.com/en-us/library/cc146437.aspx
dim newCCMUpdatesStore
set newCCMUpdatesStore = CreateObject ("Microsoft.CCM.UpdatesStore")
newCCMUpdatesStore.RefreshServerComplianceState
