FullSimply Inequalities and then rearranging them in Mathematica 7

I am using Mathematica 7 in the notebook interface and I want to rearrange an inequality so that I get a certain variable on one side. For eg.

FullSimplify[x^3+L+r>3x^3+2r]

Gives

L > r + 2 x^3

However, I want :

r < L-2x^3

Is there anyway we can instruct FullSimplify to order variables in a particular way? I am using Mathematica for presentation as well so, the way I arrange the variables is important to me.

Thanks

Edit: I tried Reduce, while that works for this example, it does not work for the actual expression I have, I get an error saying,

 This system cannot be solved with the methods available to Reduce.

Edit: here is the actual expression:

{L - (m^2 ((-2 + e)^2 \[Delta] + (5 + 
     2 e (-7 + 4 e)) \[Tau]) \[Omega])/(36 (2 - 3 e + e^2)^2)} > {0}

I want this to be displayed in the form of \[delta]< *something* Спасибо!
