Solved: Cannot load powershell module failkoverclusters in System Center Orchestrator Runbook

When I run the sctript below it works in normal powershell on the system center orchestrator server, but not in a runbook in system center orchestrator itself. I get: "The term 'Get-Cluster' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again."

. E:\scripts\GetFillingDegree.ps1

$ClusterName = "clusternamegoeshere";
$fillingDegree = 0;
$a = GetFillingDegree $ClusterName
$fillingDegree = $a.fillingDegree;

Here is the GetFillingDegree function located in GetFillingDegree.ps1:

Function GetFillingDegree {
	param([string] $ClusterName)

	Import-Module 'C:\Windows\System32\WindowsPowerShell\v1.0\Modules\FailoverClusters\FailoverClusters.psd1'
#I have also tried just: Import-Modules FailoverClusters which works in normal powershell but not in Orchestrator

To be able to load any of the modules at all I used this guide:
http://tameyourcloud.com/?p=170
That took care of the "Could not load file or assembly" error I originally had, but I am now left with the error I described above here.
