If you only need the filename then there is no need to use the -l flag on ls, which also saves you have to pipe to awk.

Code:
tail `cd path; ls -rt | tail -1`

Using backticks (`) will execute the commands between them and then substitute them with their output. So in the above the name of the most recently modified file in path will be passed as the parameter to tail.
