How to conditionally format italics without changing other parameters?

Question

I am using conditional formatting to color lines based on a priority value in column A, this works fine.

I would like to add another rule that would italicize the lines that match a specific parameter, without changing the background color the previous rules have set. When I add this rule, the background color is overridden automatically. If I place the rule after the priority rules, I lose the italics.

Is there a way to change the italicization of a line only, with conditional formatting?

Example:

Rules:

Rules                            Format
------------------------------------------------    
Priority is 3; Alcohol           Red    
Priority is 3; Beer              Red and italics
Priority is not 3                None   

Sheet:

A         B
------------
Alcohol   3
Beer      4
Alcohol   5
Beer      3
Alcohol   4
Beer      5
Alcohol   3
Beer      4
Alcohol   5
Beer      3

Formula:

=AND(SEARCH("Alcohol",$A1),SEARCH("3",$B1))

=AND(SEARCH("Beer",$A1),SEARCH("3",$B1))
