Not with 0.6.x, unfortunately.  0.7 will allow you to specify a
particular band for a specific Connection.

It will see the channels, but if you have the same SSID on both bands,
it's completely up to wpa_supplicant and the driver itself what band it
decides to use for the association, since NM doesn't pass the channel.
I'd guess that the card just reports scan results for the b/g band
first, and therefore that's the BSSID that wpa_supplicant picks.
