UDEV identical devices. How to?

Good day to all

I am not sure which list this quistions should be send to so some 
overkill maybe.

We have Debian 2.6.32 and DVB cards with two/four tunners on the each 
card. We want to assign specific number in /dev/dvb/ tree for each tuner.

The problems is that from udev point of view those devices(tuners) are 
absolutely equal(udefinfo gives absolutely identical output), because 
tuners are placed in one dvb card.

We'v googled and found that theoretically we can assign numbers in 
specific order with using ENV options in udev rules.

Here is a working example which creates symlinks:
# Create a symlinks for both tuners of Kworld device
SUBSYSTEM=="dvb", ATTRS{idVendor}=="1b80", ATTRS{idProduct}=="e399", 
ENV{kworld}!="two", ENV{kworld}="two", PROGRAM="/bin/sh -c 'K=%k; 
K=$${K#dvb}; printf dvb/adapter_kw1/%%s $${K#*.}'", SYMLINK+="%c"
SUBSYSTEM=="dvb", ATTRS{idVendor}=="1b80", ATTRS{idProduct}=="e399", 
ENV{kworld}=="two", ENV{kworld}="one", PROGRAM="/bin/sh -c 'K=%k; 
K=$${K#dvb}; printf dvb/adapter_kw2/%%s $${K#*.}'", SYMLINK+="%c"

But we do want devices instead of symlinks, like e.g. /dev/dvb/adapterX

We'v tried such rules, but has no luck:

SUBSYSTEM=="dvb", KERNELS=="0000:04:00.0", ENV{kworld}!="two", 
ENV{kworld}="one", PROGRAM="/bin/sh -c 'K=%k; K=$${K#dvb}; printf 
dvb/adapter1/%%s $${K#*.}'", NAME="%c", GROUP="video"
SUBSYSTEM=="dvb", KERNELS=="0000:04:00.0", ENV{kworld}=="two", 
ENV{kworld}="one", PROGRAM="/bin/sh -c 'K=%k; K=$${K#dvb}; printf 
dvb/adapter2/%%s $${K#*.}'", NAME="%c", GROUP="video"

Can someone give an advice how to properly construct rules to assign 
devices. It woul be great with an example string
Mb we missing some global udev option to enable such constructions?

Tnx in advance.
