If money are not the issue, I would just buy a new one, and keep this one as a spare or a trainer tire. 100 PSI doesn't sound much, but it's a lot of pressure trapped in a very small space.
Someone mentioned "tire boot" - pretty good idea to make sure tube have a good support near the damaged spot. You decide.
