DiMarzio doesn't make dedicated 'neck' and 'bridge' versions of their pickups, like Duncan does, but you can use many of their common neck pickups like the PAF Pro as low gain bridge pickups -- jazz cats use the Air Norton in the bridge, and the DiMarzio website says that Korn uses the PAF7 in the bridge because the lower output gives a clearer sound with all their amp distortion.
one thing to watch out for when swapping pickups from the neck position to the bridge is whether the magnet was flipped. pickups like the PAF have one coil of screw head pole pieces and another coil of 'slug' flat poles. to install this type of pickup the right way in the neck position, with the screw heads closest to the fingerboard, and to get the right magnet polarities for hum canceling coil cut combinations like the Ibanez 5-way switching for two humbuckers, you need to flip the magnet in the pickup. [unscrew the bottom plate of the pickup, CAREFULLY pop the magnet out, rotate it 180 flat, and slip it back in. the magnet polarity should be opposite of the bridge pickup, so the screw poles of neck and bridge should attract each other if you hold them close].
this isn't an issue for H/S/H configurations, since you want the humbuckers not to have opposite polarity so each of the inner coils will hum cancel with the middle single coil. [unless you use a Schaller Megaswitch, and then you do need to flip...] it also doesn't matter with a pickup like the Blaze II, that has the same pole pieces on both coils -- it will look the same whether installed 'backwards' or not.
so if your 3120 has 5-way coil cut combinations and the PAF Pro screw poles closest to the fingerboard, that pickup probably had the magnet flipped at the factory. if you put it in the bridge position, you might not get all your middle switch positions hum canceling unless you re-flip the magnet.
