I compiled 3.4.3 from source. This does seem to work now, albeit slow to
fall back.
I think I should have searched 'squid happy eyeballs' first. Apologies,
finding more details now and reading into it.

FYI - anyone wanting to test any of this, here is a great site:

Hello,
I'm running 3.1.19 (from Ubuntu 12.04 package). squid does a great job
of picking ipv6 first and using that (for sites that have AAAA and
respond).
The problem is when a site's ipv6 connectivity is broken - squid doesn't
fall back to ipv4. An example at the moment is isc.sans.edu. I
contacted them and they may fix this by the time folks read this message
though.
There have been a number of small issues in this area found and fixed as
of the latest 3.4.3 release. Please try an upgrade to the latest you can.
