Steps to reproduce:
1. create a mxml with the following tag

<s:VGroup id"testGroup" x="10" y="100">
<S:Button label="Btn1111111111"/>
<S:Button label="Btn2222222222" rotation="270"/>
<S:text="Label1111111111111111"/>
<S:text="Labe2222222222222222" rotation="270"/>
</sVGroup>

2. Set teh appllication to use layoutDirection="rtl" direction="rtl"
