How to sort the word which has a dot . and paranthesis() using powershell

I want to sort out all the words which has the below structure :

.getMethod(param);

.getMethod1();

The structure is a . dot followed by word which is followed by () paranthesis and ; semicolon.

$WordList = @(
    '.getMethod(param);'
    '.getMethod1();'
    '.putthis(that);'
    '.getthis();'
    '.getthis(that);'
)
$WordList | sort 

Thanks Sam . Will give it a try .
