Retina, score 1
The empty program counts the number of matches of the empty regex in the input (which is the empty string). That's exactly 1 match, so it prints 1.

Pyth, 10
T
First attempt at using Pyth. Having had the question clarified, it seems 10 will be the smallest number. In Pyth the letter T starts off as the number 10, so this simply prints 10 which is larger than the length of the source code. You can try it here.

Hopefully I've got this right - it's my first time programming in Ruby. I actually did all my testing in Python, but import re was far too long for me.
This is an anonymous function which takes in a string and outputs true/false accordingly. It uses a regex which looks for one of the following two things:

Luckily, bc prints the result of the last expression by default. A is interpreted as a hex digit, so results in 10.

(EDIT: This first part refers to the original phrasing of the question.)
First, (!x&&!y&&!z) returns a boolean, which makes ?true:false entirely redundant. It's basically like using
if (x == true)
return true;
else if (x == false)
return false;
instead of return x;.
That gives you
!x&&!y&&!z
