Check out the ROTATE_ABOUT_POINT mode with either a Billboard or
OrientedShape3D. It has the property you are after: the +y axis of the text is
kept aligned with the +y axis of the view, so the text is always right side up.
Combine this with the basic billboard property of aligning the +z axis if the
text with the eye vector, and you'll find that the text is always the way you
want it.
BTW, you don't need to worry about the text being backwards (i.e. being flipped
along the x axis so that the text +x axis aligns with the view -x axis), since
that transformation would require -1 scaling along the x axis and the billboard
transform is rotation only. +z out and +y up implies +x is to the right as long
as there are no negative scales in the transformation.
