Check out Cisco's SRNDs for info on this. There is also a great
Networkers presentation called "Experience in IGP Scaling", or something
like that.
In short:
1) EIGRP scales better in very large hub-and-spoke networks, given
proper design (EIGRP stub, summarization, filtering, etc.). It is
especially good for stuff like large DMVPN networks. You also don't have
the same sorts of restrictions that you have with area design in OSPF.
2) OSPF (or IS-IS) is required for MPLS TE.
Here's one document that talks about routing protocol selection in
campus design:

Subject: EIGRP or OSPF
What reasons should I use EIGRP over OSPF? I am told that if all
devices
are Cisco, then EIGRP is a better protocol to use. Just as general
practice,
I'm curious as to what people are doing in production environments.
