Ian wrote about this issue back in September: http://ianblythmanagement.wordpress.com/2013/09/12/sql-server-2012-db-engine-group-problem/
Essentially – SCOM discovers the SQL Version from a registry key that SQL places. The problem arises that the SQL version in that key uses a different SQL version that what is considered typical.
SQL build versions are visible here: http://sqlserverbuilds.blogspot.com/
When you apply SQL 2012 SP1 to SQL 2012, this updates the registry from 11.0.xxxx.x to 11.1.xxx.x as seen below in SCOM Discovered inventory:
The issue is that the group “SQL Server 2012 DB Engine Group” is hard coded to 11.0.* as seen below:
I wrote a quick MP that contains a new group population discovery set to “11.*” along with an override to disable the built in group. The XML is visible below:

I will also attach the MP as a zip file to this post below.
Now my groups populate as expected:
