Or, you could simply change isalpha to isalnum and recompile.

The splitter (which is written in C for textindex) omits numbers. The code 
that does this can be easily commented out though. Specifically this section

of 
{Zope}/lib/python/Products/PlugInIndexes/TextIndex/Splitter/ZopeSplitter/src
/ZopeSplitter.c

    /*************************************************************
      Test whether a word has any letters.                       *
                                                                 */
    for (; --len >= 0 && ! isalpha((unsigned char)cword[len]); )
        ;
    if (len < 0 && ! self->index_numbers) {
        Py_INCREF(Py_None);
        return Py_None;
    }

    /*
     * If no letters, treat it as a stop word.
     *************************************************************/

Comment this out and a recompile, restart and reindex will get the numbers 
indexed.

ZCTextIndex in Zope 2.6 indexes numbers by default (Hands waving in air ;^).
