amazon simple admin/ tablepress price order

I am currently using Tablepress to show my products which are generated through Amazon simple admin. I have managed to hack the theme about so that the two work together perfectly.

However I cannot get the price column to actually go in the correct ascending/descending order.

Is there a work around to allow the price to be sorted correctly?

I should also mention that because I’m using Amazon simple admin, I’m not putting actual numbers into the backend of Table press, I’m putting a kind of shortcode;

e.g [asa Buy]B0115SHKNU[/asa]

The buy being my own hacked version of the default template which is basically saying take only the price from the product code.

If the above doesn’t help, my table can be seen at http://www.fast-protein.com

Thanks!
