or if you really do want it as a plugin

Plugin:
(function($){
  $.fn.stringCount = function() {
var string = this.text();
       var count = string.split(" ");
       var result = count.length;
return result
  }
})(jQuery);

Use:
$(function(){
   alert( $("span.string").stringCount() );
});

you don't need a plugin, this will do it

var string = $("span.string").text();
var count = string.split(" ");
alert(count.length);

Any jquery plugin can check number of word in a string instead using of .length?...
