I could not load sos.dll in Visual Studio 2013 no matter what I tried.
Instead, I used the good old WinDbg. I know this is not an ideal answer, but it seems to be the only possible solution for debugging using sos.dll. I would really like to use sos.dll in Visual Studio 2013, but WinDbg is not so bad as soon as you learn its basics. It is really very powerful, even if you know very little about an uncontrollable world (like me).
