I've mocked this up in my lab and don't have a problem with it.
I didn't add the split-horizon configs but I wouldn't expect split-horizon
to cause problems over these the virtual interfaces.
Do your route tables on R1 and R5 show R3 as the next-hop for these
loopbacks? Can you ping the loopbacks from R3?

Subject: Can't ping between two EIGRP frame-relay spokes
I can ping all routes save two in my topology. The two routes I can't ping
are in the routing tables of the spoke routers, but pings from spoke to
spoke get black-holed at the hub frame router.
I know this is a frequently-encountered problem, and I thought I could solve
it by disabling ip split, but nothing I do works.
Can one of you help?
Briefly, I have R3 as the hub and R1 and R5 as spokes. I am using PPP over
FR using virtual templates. The adjacencies all form and I can ping all
routes except 150.1.1.1 and 150.1.5.5
Here's my config:
