If you only want to get the number into TRACK and leave TITLE as it is, you could try an action of the type "Format value" or the function Convert>tag-Tag, both for TRACK
Format string: $regexp(%title%,^(\d+).*,$1)
If you want to move the number to TRACK and also see the TITLE without it, try and action of the type "Guess value" (import tag fields)
Source: %title%
Pattern: %track% %title%
PS: I think the correct title would be "It's never too late"
