tagging files: one rules works, one not

Hello!
I have a PDF-file named "Rechnung 20130823 Kopfhörersplitter.pdf" (= bill 20130823 Headphonesplitter) in a folder "... /Rechnungen/Hardware/2013" (= bills/hardware/2013).
I have the following Hazel-rules for the folder "Rechnungen":
1.- run rules on subfolders (as here described: http://www.noodlesoft.com/forums/viewtopic.php?f=4&t=470)
> IF: kind is folder
> DO: run rules on folder contents
2.- tag "rechnung" for all files
> IF: any file
> DO: add OpenMeta tags "rechnung"
3.-"Rechnung 2013..." --> tag "2013"
> IF: file name contains "Rechnung 2013"
> DO: add OpenMeta tags "2013"
The third rule doesn't work and I can't figure why.
Do you have any idea?
Thanks!
Kind regards,
