+1 to that.  (ISC isn't extremely common, but it's not rare, and a bunch of commonly used ports do use it.)

The main distinction which matters for BSD licenses is whether the "acknowledgement" clause (aka clause 3 of the 4-clause license from FreeBSD's /COPYRIGHT) is present, since that makes it not miscible with GPLv2.

In your particular case, you don't have the "acknowledgement" clause.

Considering that there are ~4000 p5 ports, it seems reasonable to indicate that they are licensed under the same terms as Perl itself.  Similar arguments might be made for Python or Ruby, but I'm not sure they're as common.

I see "MIT" listed, although I would describe it more precisely as the MIT/X11 variant rather than a pure MIT license.
