Hi Max,
In fact it does. You can query bond orders with $sel getbondorders,
alter them with $sel setbondorders, and visualize them using the Bonds
representation. However, please note that many file formats (for
example, pdbs) *don't* carry information about bond orders, nor do the
structure files for most MD programs. Any file format supported by VMD
which does include bond order information should work properly.
