Root cause explanation:

Line 3766 of Minescript.java:

LOGGER.info("Matched {} command(s) with autorun[{}]", wildcardCommands.size(), worldName);

Should be:

LOGGER.info("Matched {} command(s) with autorun[{}]", worldCommands.size(), worldName);

Workaround

Instead of this config.txt:

python="/usr/bin/python3"
autorun[PvE nerd.nu]=example pve

Use this workaround:

python="/usr/bin/python3"
autorun[*]=autorun

The autorun.py module:

import minescript
world = minescript.world_info()
if world.name == 'PvE nerd.nu':
    minescript.execute("\\example pve")
elif world.address == 'other.example.com':
    minescript.execute("\\example other")
