new management scope based on database and organizational unit

hi

i have some exchange 2010 SP servers and want to delegate some tasks to some other guys so wanna use RBAC

i want those guys to have some commands in an specific OU and specific databases cause in that OU there are some people with a database i do not like to be touched and also that database has some mailboxes with users in other OU's

so i want filter on both database and OU but this command does not work

New-ManagementScope -Name "Test" -RecipientRoot "domain.com/myou" -RecipientRestrictionFilter {RecipientType -eq "UserMailbox"} -DatabaseRestrictionFilter {Name -Like "db*" }

Error

Parameter set cannot be resolved using the specified named parameters.
    + CategoryInfo          : InvalidArgument: (:) [New-ManagementScope], ParameterBindingException
    + FullyQualifiedErrorId : AmbiguousParameterSet,New-ManagementScope

but when i do this separate foe each one it works

i mean this works

New-ManagementScope -Name "Test" -RecipientRoot "domain.com/myou" -RecipientRestrictionFilter {RecipientType -eq "UserMailbox"}

and also this :

New-ManagementScope -Name "Test" -DatabaseRestrictionFilter {Name -Like "db*" }

but along together, :-? the error above
