Gavin,

Did you see my message where I said that I got the following to work?
Admittedly I haven't run a comprehensive suite of test cases over it.

NUMBER
:    '0'
|    '0' ('0'..'7')+        // An octal integer
|    '0' 'x' HEXDIGIT+    // A hexadecimal integer
|    SIGN? '1'..'9' DIGIT*    // A decimal integer
|    SIGN? DIGIT+ FRACTION    // a real number
|    SIGN? DIGIT+ EXPONENT
|    SIGN? DIGIT+ FRACTION EXPONENT
|    SIGN? FRACTION EXPONENT?
;

... with the range grammar I shared earlier.
