There had been a SCOM pack developed for SCOM 2008 and also provided limited NIOS 5.x support for 2010. Microsoft changed the discovery process in SCOM 2012 which rendered the previous plug-ins invalid. There have been requests for 2012 support but this has not been developed. 

If updated SCOM support is something you would like to see, I suggest contacting your account team to ensure your organization is added to the appropriate RFE!
