You've enclosed each word of your selection string in its own set of single quotes. You need to enclose the whole of your selection string - including the name of the selection -  in one set of single quotes. This forces your shell to pass the whole string as the argument to -select. Normally the shell breaks up the words before the tool you are using gets a look at them.
