Mini USB receptacle versus proper PCB layout
I've noticed the same problem when routing boards with the FTDI FT232 chips. Here's what the CY7C68013A datasheet says about routing those signals:


  
  DPLUS and DMINUS trace lengths should be kept to within  2 mm of each other in length, with preferred length of 20 to  30 mm.
  Maintain a solid ground plane under the DPLUS and DMINUS  traces. Do not allow the plane to split under these traces.
  Do not place vias on the DPLUS or DMINUS trace routing.
  Isolate the DPLUS and DMINUS traces from all other signal  traces by no less than 10 mm.
  


I would suggest the zig-zag method, but only if it that little detour around the pin added more than 2 mm to the trace length.
