[LARTC] can I use tos and fwmark at the same time?

Hello lartc maintainers and users!
  I have a router with two NICs. One NIC is connected to the Internet and the other to my internal LAN. I made a script for priorizing interactive traffic. The script matches TOS Minimize-Delay for priorizing interactive trafic, and fwmark for metropolitan packets.
 I have two root classes (simulating two circuits) : 1:1 for internet and 1:3 for metropolitan.
 When I watch -n1 tc -s -d qdisc show, the classes that belong to metropolitan traffic (FE) on the two interfaces are not sending nor receiving any byte...
 Can someone help me out this situation? I list my tc and iptables scripts below (for some reason I could't attach them - "Invalid file").
 Thank you in advance!
