Mac OS X may not be as simple as it appears. I believe 10.5 offers
32-bit OS that is capable of running 64-bit binaries.

You might need something that considers both hw.cpu64bit_capable and
hw.optional.x86_64. I believe you need to use hw.optional.x86_64 to
determine if 32-bit OS can run the 64-bit binaries.

A good discussion is at "determine if a CPU is Intel 64-bit,"
