I don't know if I understand the problem completely but two solutions
see possible:
1. Manual approach - configure eth) not to come up on boot. If the
wlan fails then bring up eth0 manually.

2. Configure both interfaces not ot come up on boot. In
/etc/rc.d/rc.local place a script that first tries to bring up the
wlan0. If the fails the eth0 interface is brought up.

ifup <interface name>  brings up interfaces.
