"Uncaught TypeError: Cannot call method 'isArray' of undefined"

Using jQuery 1.8 and Pickadate, I get an error on line 191 of picker.date.js:

Uncaught TypeError: Cannot call method 'isArray' of undefined

// If it’s an array, convert it into a date and make sure
    // that it’s a valid date – otherwise default to today.
    else if ( $.isArray( value ) ) {

If I change all instances of '$.' to 'jQuery.' in the script, then it works without an issue.

I am using this within Drupal 7.23 if that matters - I believe this is a scope issue but not sure where to correct it.

For reference, here is the module I am building.

Nothing special about the JS invocation.

Here is a Zurb plugin I integrated recently, I did not change anything about the script whatsoever and it works.

Fixed in v3.3
