Thanks, Tomi.

While I learn enough elisp to dive into those hooks, I've solved my
need to move files according to tags with the following pre-new script,
which recycles parts from other scripts around:

#!/bin/bash

echo "[pre-new] Syncronizing tags and folders... "

path=/home/jlaznarte/mail/UNED/
exclude='signed attachment spam draft flagged passed replied unread encrypted deleted'
count=$(notmuch count 'folder:Inbox and not tag:inbox')

# Move a message file while removing its UID-part
function safeMove { s=${1##*/}; s=${s%%,*}; mv -f $1 $2/$s; }

if [ $count = 0 ]; then
    echo "[pre-new] No messages needed moving."
    else
        echo "[pre-new] Moving" $count "messages to their corresponding folder."

	for message_id in $(notmuch search --output=messages \
	    'folder:Inbox and not tag:inbox')
	do
		# Find the tags of the message that we need to move
	        tags_orig=$(notmuch search --output=tags $message_id)

	        # Remove notmuch special tags
		# (do not correspond to folders)
	        tags=$(tr ' ' '\n' <<< "$tags_orig" \
		    | grep -vf <(tr ' ' '\n' <<< "$exclude") | paste -sd ' ')

		# Get the path and filename for the message
	        filename=$(notmuch search --output=files $message_id)

	        echo "Moving message to" $tags
		safeMove $filename $path$tags"/cur/"
	done
fi && mbsync
