org.freedesktop.NetworkManager.IP4Config object of a device is 
read-only and shows active IP parameters.

If you want to set up routes (or addresses), you should update a connection
(or create a new one) and then activate it on a device.

see:
http://projects.gnome.org/NetworkManager/developers/api/09/spec.html#org.freedesktop.NetworkManager.Settings.Connection
It accepts all new settings, so you need to obtain the connection and change 
the parameters you want.
This example changes Ipv4 address:
http://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/examples/C/qt/change-
ipv4-addresses.cpp

You can also look  at python examples at:
http://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/examples/python
e.g. add-system-connection.py, which work with 'addresses' that are similar to 
'routes'.

you are interested in routes property of 'ipv4' setting here:

settings.html#id409163
