[:digit:] matches any one of the characters ':', 'd', 'i', 'g', 't'.
What you need is
[[:digit:]]
.
It worked

From the Help on "How to Use Regular Expressions:
Character Class Operators "[: ... :]":
These can be used in class expressions as an alternative way of representing classes of characters. For example, [a-z0-9] is equivalent to [[:lower:][:digit:]]. (Note the extra pairs of brackets.)
Shouldn't the help documentation have double brackets?
