It's not necessary to do this. You can simply be happy about the fact
that all digits are ordered strictly in unicode, so you can use a range
query:
(f)q={!frange l=0 u=\: incl=true incu=false}title
This finds all documents where any token from the title field starts
with a digit, so if you want to only find documents where the whole
title starts with a digit, you need a second field with a string or
untokenized text type. Use the copyField directive then, as Jack
Krupansky already suggested in a previous reply.

If you are not searching for the specific digit and want to match all
documents that start with any digit, you could as part of the indexing
process, have another field say startsWithDigit and set it to true if
it the title begins with a digit. All you need to do at query time then
is query for startsWithDigit =true.
