The thing is, is that there is a link between thermodynamics and disorder. This is the tour de force result of statistical thermodynamics vs classical thermodynamics - i.e. that the macroscopic quantity which we can measure called "entropy" is related to the number of possible microstates the system can explore. As has been correctly pointed out, the problems start when we directly equate this with "information", or entropy as defined in information theory i.e. "Shannon entropy". This is an analogous concept, based on the fundamental information content of a system. But there isn't an equivalence between information-theoretic entropy and thermodynamic entropy. In the actual physical world, there is no need to directly connect the quantities of "disorder" and "information". This, in part, along with the more important facts that all these things apply to closed systems and the Earth is not a closed system, means that any argument based on how "entropy" disproves evolution due to some information argument is bogus.
