I think it's only a matter of passing the right config file on the 
rotate call using the -f option so the temporary app can send the rotate 
to the right PID.

I'd merge the two configs together too so they are handled the same way 
no matter what.

/etc/logrotate.d/squid:

#
#       Logrotate fragment for squid (both 1 and 2).
#
/var/log/squid/*.log /var/log/squid2/*.log {
        daily
        compress
        delaycompress
        rotate 90
        missingok
        nocreate
        sharedscripts
        postrotate

 test ! -e /var/run/squid1.pid || /usr/sbin/squid -f 
/etc/squid/squid1.conf -k rotate

 test ! -e /var/run/squid2.pid || /usr/sbin/squid -f 
/etc/squid/squid2.conf -k rotate

        endscript
}
