HRESULT 0x80070001,Register-ClusteredScheduledTask

I'm trying to define a ClusteredScheduleTask on a cluster, running Powershell on the active node.

Code:

$trigger = New-ScheduledTaskTrigger -at 12:00 -Once
$action = New-ScheduledTaskAction -Execute "notepad"
Register-ClusteredScheduledTask -Action $action -TaskName "clusteredtasktest" -Trigger $trigger -TaskType anynode

Error:

Register-ClusteredScheduledTask : Incorrect function.
At C:\Users\nwalters\Documents\TestWebSampleCode2.ps1:3 char:1

Posted here first: http://serverfault.com/questions/623407/powershell-set-clusteredscheduledtask-error-incorrect-function

Still not getting any definitive answer. This is one of the few things remaining before switching our production code to this cluster.

Thanks,
