I know this is an old post, anyway for the records: 

even now (feb 2024) this is not working and it's probably some kind of bug in regexp parsing by Sign, because the syntax is working when combined in more complex formulas, anyway you can use a working synonym as:

 

^[0-9]{6}$

 

this works. Why not the other? Dunno.
