Which eth NIC for correct network connection?

I work at school and I need 5 network zones.

Now, I test ASL with:
LAN1 (eth1 - down) green zone - for administration and teachers PC
LAN2 (eth4 - up) green zone - for students PC
DMZ1 (eth2 - not define yet) orange zone - for administration and teachers public servers
DMZ2 (eth0 - up) orange zone - for students/experimental public servers
INTERNET (eth3 - up) red zone - for INTERNET connection

All work right, but I have a question.

Do it be important for ASL what NIC (eth) connect for which network?

I know, that recommendations are in order to:

eth0 - LAN
eth1 - external/INTERNET
eth2 - DMZ

but.... I would like to make it write so as earlier if it doesn't matter.

I have checked "Current Packet Filter Rules" and I can't find chain where it is used rule with option "in" or "out" other than "*"
( I found only eth4 for BOOTP service)

In terms of convention, the first one is usually the (first?) internal network (since an install points to that as an administrative admin by default) and the last is usually the Internet; but it's like what's an appropriate color to paint your house -your technically free to do anything, though some colors are more conventional than others...
