Hey see this thread for a more in depth discussion
http://www.dakkadakka.com/dakkaforum/posts/list/575701.page
But from my understanding heres a paste of my comment:
Games workshop digital have stated as answers several times that the genestealers ARE scoring units
------------
example:
Q:Hey I just downloaded the dataslate and I like it a lot! A question, though - the manufactorum genestealer formation says broods may not add genestealers - can I add brood lords to those units? Also do they count as troops for scoring objectives? Thanks!
A-Hey Jonathon,
The unit is the same as the one that appears in the codex in all regards, so the unit's battlefield role stays the same as do any options that aren't specifically mentioned as being changed.

*to find this specific comment its a comment on the post that has an image of the planet with the words 'the fall of satys'
but there are others too
---------------
This is a similar answer they give to all questions asked relating to genestealers form formations as scoring units
But also this indicates that perhaps Manufactorum genestealers can in fact include additional broodlords
As the dataslate mentions they cannot include more genestealers, but no mention of upgrades such as a broodlord.
Curious to hear opinions on this, but from the answers they are giving, genestealers form formations can score, and manufacotrum genestealers can in fact include a broodlord
Cheers
