One way to look at is that currently we only have data on the correlation between her tail twitches and falling objects, but not on the causation involved.
Given this we have two scenarios “Something about her tail twitches causes things to fall” or “Items falling can cause her tail to twitch in the past.”
The first option is actually more consistent with the known physics of the world, as it doesn’t require anything thought to be impossible like precognition or backwards causation. And it would fit pretty closely to the known phenomena of ponies using magic, often involving them moving their bodies, to move distant objects. So it is plausible she is performing subconscious magic.
Ponies in the show can generally be divided into unicorn-pegasus princesses, unicorns, pegasi, and “earth ponies” who have neither horns nor wings. Pinkie Pie is an earth pony. If Pinkie Sense is magic, it would be the only known instance of an earth pony performing magic.
