You can use the 'pkg set -o ...' command, but I suspect the version change is not happened automatically because the default in your poudriere is not set to perl5.22

# pkg set -o lang/perl5.20:lang/perl5.22
(note old <--> new swapped and separated with ':' )

>From Mk/bsd.default-versions.mk:
...
PERL5_DEFAULT?= 5.20


To overwrite this in PD globally
$ cat $LOCALBASE/etc/poudriere/make.conf (or $set-make.conf, for only a dedicated ports set)
DEFAULT_VERSIONS+= perl5=5.22

and fire a new build, all ports depending on the default perl are reflecting the new 5.22 version as dependency and the perl version should change automatically.
>From my past experience with perl upgrades I would run 'pkg upgrade -f' else not all p5-$ports are reinstalled.
And as super bonus since you are already building with PD you don't have to mess around with portmaster


PS:
nice writeup on your webpage, to get a even smaller package list you can run "ports-tools/pkg_tree" with the parameter '-t'
