I found a solution and I have posted it at http://gentoo-wiki.com/Talk:HOWTO_Install_a_USB_scanner#.22The_above_udev_rules_are_wrong..22.
If anybody who knows their hotplug and udev stuff better than I do could take it upon themselves to correct the usb scanner howto itself (http://gentoo-wiki.com/HOWTO_Install_a_USB_scanner), which is very confusing and misleading, I'm sure there will be good few people out there who will be very grateful to you. (And not just Gentoo users -- there is a real lack of up-to-date usb scanner documentation out there.)
