I do this with a2dp, I'm sure the same could apply to sco.
I use an .asoundrc file which looks like this:
pcm.a2dpd {
=A0=A0=A0=A0=A0=A0=A0=A0type a2dpd
}
pcm.rs0 {
=A0=A0=A0=A0=A0=A0=A0=A0type plug
=A0=A0=A0=A0=A0=A0=A0=A0slave {
=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0pcm "a2dpd"
=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0rate 44100
=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0format S16_LE
=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0channels 2
=A0=A0=A0=A0=A0=A0=A0=A0}
}
pcm.!default {
=A0=A0=A0=A0=A0=A0=A0=A0type plug
=A0=A0=A0=A0=A0=A0=A0=A0slave.pcm "rs0"
}

It will resample the audio given to the a2dp plugin so it is always 44.1kHz.
Cheers,
Tim
