Are you sure that your routers do not respond to the default source address 
0.0.0.0 arping request?  Have you tried changing this to:

gateways_eth0=( "192.168.1.254 192.168.1.1" )

The option -0 negates the -S 192.168.1.114.  Use one or the other.

If it works with option -0 then use my suggested format for gateways_eth0= 
because you do not need to spoof the arping address.
