Here is a link to information on the Taylor web site to decode the serial numbers. From it you should be able to determine the manufacturing date of the guitar. Based on your statement that it is an 11-digit serial number, the guitar was manufactured between 2000 and 2009; Taylor switched to a 10-digit serial number starting in 2010. Custom (or "BTO") Taylor guitars follow the same serial numbering scheme.
Barring an error on the label, I'm wondering if the 'custom' order was just a request for some options that could be selected at that time: for example, the three-piece back, and an
Expression System (ES) with no-controls. Does the guitar have a strap pin on the bottom of the body that is black plastic, and looks like it can accept a 1/4-inch jack? If so, you may have an ES installed, but there are no knobs with which to control it. This was an optional configuration of the ES. Given the range of years your guitar may have been manufactured, it's hard to say which version of the ES could be installed.
