We have the same problem here you've been describing in your email some 
months ago. Our books have a long 11 digit barcode but only 4 were stored 
in our old system. A barcode looks similar to yours, like I1025059820 
where the first digit I is used for books or B for patrons, the following 
4 digits are the same for everything and the last digit must be a check digit.

We're running Koha 3 and as you say only have the choices "whitespace", 
"T-prefix" and "cuecat".

Did you get this to work eventually?

Cheers,
