3mm difference between the two eyes is definitely possible, especially in the case of strabismus or a similar disorder.
More importantly, though, where did you get the PD measured, and how long ago? With conditions that can cause such divergent numbers, PD can change over time - and can even change substantially depending on whether you're looking at something close up or far away. Prior to corrective surgery, my eyes were 30/32. Following the surgery, I was measured at 64 even, but find 65 to be more comfortable and improve my depth perception. So, Pd can be a really tricky thing. I've seen several online vendors that let you specify a different PD for each eye, but I can't recall which ones offhand - check the ones often mentioned on this site, you should be able to find one.
