Given: client machines running windows 7 / 8 / 8.1
openvpn client (the last one from the community site)
When connecting to the Internet, two DNS servers are assigned: 8.8.8.8 and 8.8.4.4. Then, when connecting via OpenVPN (tap interface, if it matters), two more DNS servers "fall" from the vpn server: 192.168.50.10 and 192.168.70.10.
From the output of ipconfig / all you can see that the first two "hang" on eth, and the second two on tap.
How to make a DNS client on a computer look up DNS servers in the following order:
192.168.50.10
192.168.70.10
8.8.8.8
8.8.4.4
Addendum: On GNU/Linux and OS X clients, /etc/resolv.conf is simply overwritten when the client connects to the OpenVPN server and restored afterwards. It is also clear how to change this behavior on these OSes. But as in Windows - no.

If I understand the question correctly, then when the OpenVPN client connects to the server, the server issues only 2 server dns addresses, but 4 are needed.
If so, then these dns must be added in the OpenVPN server configuration file.
config file usually in /etc/oepnvpn/server.conf
push "dhcp-option DNS 192.168.50.10"
push "dhcp-option DNS 192.168.70.10"
