tag update with several tags

[artwo]

I have the following rules but it doesn't work:

Quote:@CUSTOM1=2017
&RATING=5
+CUSTOM1=Best of the moment

@RATING=1
=RATING=≈
@RATING=2
=RATING=≈
@RATING=3
=RATING=♪
@RATING=4
=RATING=♫
@RATING=5
=RATING=♫♫♫

@CUSTOM1=2017
+CUSTOM1=Récent
@CUSTOM1=2016
+CUSTOM1=Récent

"Recent" rule and "Rating rule" do work. The first one doesn't.
