EIGRP metrics are calculated based on the values used on the outgoing
interfaces towards the destination, and the composite metric is
calculated separately in each direction.

If you want the spoke to prefer the path via one tunnel over another,
you'll need to manipulate the metrics on the spoke's tunnels.

On the spoke:

interface Tunnel0
 delay 1000
!
interface Tunnel1
 delay 2000
