Numbers for .max method are compared as strings

When using Drupal's integer field with a maximum value set, the values are compared as strings instead of numbers. The JS inserted into the head tag has the maximum values quoted.

I've been able to workaround this by updating the local jquery.validate.js file as follows:

--- a/jquery.validate/dist/jquery.validate.js
+++ b/jquery.validate.orig/dist/jquery.validate.js
@@ -1226,7 +1226,7 @@ $.extend( $.validator, {
 
                // http://jqueryvalidation.org/max-method/
                max: function( value, element, param ) {
-                       return this.optional( element ) || Number(value) <= Number(param);
+                       return this.optional( element ) || value <= param;
                },
 
                // http://jqueryvalidation.org/range-method/

It would seem to work without this modification if the values sent to the jQuery Validations max method were not quoted.
