Meta Values Searchable and Sortable?

Hi everyone. I’m somewhat new to developing for WordPress and I need some help.

I’m using hooks on the search function to make it also search for the keyword in meta values, but when doing this, the search is not sortable by meta value using query_post() arguments. It’s sortable by meta value when I comment out the hooks, but I need them both to work at the same time. In short, how can I make it so that meta value is searchable AND sortable?

Let me know if you need me to elaborate…I wrote this in kind of a hurry.
