If they terminated your contract last week, you are no longer employed by the company and you cannot be on gardening leave. As to whether the PILON is taxable depends largely on what exactly your employment contract said about your entitlement to notice and whether the company was entitled to pay you in lieu of notice.
Your former employer is playing safe by deducting PAYE, and there is little you can do to stop them. If the PILON should have been paid without PAYE, your best bet is to complete an SA return (after 5 April 2012) and claim the tax back that way. (You will of course be out of pocket for the best part of a year). HMRC will want to see your employment contract and all the correspondence around the termination, to check if the PILON is taxable. You may need professional help, as HMRC is unlikely to decide in your favour, in the first instance.
