Do you mean you want to change the string into "(x[1] & (x[2] || x[3]))" ?
Does it have to be using regular expressions? Would this be good enough?
>>> s = "(1 and (2 or 3))"
>>> for c in '123':
... s = s.replace(c, 'x[%s]'%c)
...
>>> s = s.replace('or', '||')
>>> s = s.replace('and', '&')
>>> s
'(x[1] & (x[2] || x[3]))'
