isotope plugin

isotope plugin

Hi everyone,
I am using the isotope plugin: ( http://isotope.metafizzy.co) in a project.
It sorts elements quite nicely.
They have a sorting method for elements called random.


When I use the random function all the items sort as they should.

My problem is: 
I want to select the visible elements in the order they are seen after sorting randomly.

Please let me know if you have any ideas or tips!
