Eldritch Scion & Bloodrager

[redviiper]

If I have levels in both do they both add up for what bloodline powers I get?

No, you'd have two separate uses and abilities, but the bloodlines would need to be the same.
Eldritch Scion 4/ bloodrager 1
So bloodrager rage to get claws as lv1 claws.
Eldrich scion can get claws at a lv4 bloodrager.
this faq is where this ruling is cleared up.
