I've found this too with other cloned interfaces, vlans for me.  I
use the following trick to work around the problem of not being
able to set the address and other configuration at the same time:

ifconfig_vlan1000="vlandev em2 vlan 1000"
ifconfig_vlan1000_alias0="inet 10.0.0.1/24"

So for your case, I'd do:

ifconfig_lagg0="laggproto failover laggport sis2 laggport sis0 \
	laggport sis1"
ifconfig_lagg0_alias0="inet 192.168.3.97 netmask 0xffffff80"

I'm not sure why it doesn't work the way you'd expect to.
