It's not supposed to -- userspace does not generally (AFAIK anyway)
handle management frames of any kind.

Try looking at the various different ap_scan modes; it sounds like you
want one where the driver does the scanning and roaming.  But note that
not all drivers support all modes (or at least, I've heard that not all
of them support ap_scan=2, anyway -- I only use the Windows port at
work, so I only have to deal with the NDIS driver, which does support
that mode).
