Looking for a way to recompose on a reoccurring schedule

I am looking for away to schedule a recompose through PowerCLI or some other scripting method. I had found the script below and tried it out but it would not work. After placing a call to VM I am being told that "Get-Pool" is not a command. I find this odd as it is a command listed in their PowerShell Integration guide. So with that said does any one have an alternative?
