Does modern 6500 IOSes still have the restriction that not more than 10 L4OPs are allowed per ACL? I don't see this behaviour:
DSW100(config)#do sh tcam int vlan 12 acl out ip
* Global Defaults shared
permit tcp xx.13.62.0 0.0.0.31 172.16.112.0 0.0.0.127 range 100 pop2

permit tcp xx.13.62.0 0.0.0.31 172.16.112.0 0.0.0.127 eq www
This all fits into the PFC2.
