How about this:

#!/bin/bash

# fails if bash changes "GNU bash, version " prefix
VER=$(bash --version | head -1 |cut -c19)

case $VER
  1,2)
       echo "Fails"
       ;;
  *)
      echo "http://xkcd.com/{1..327}"
      ;;
esac

If the {n...m} syntax changes in a future version of bash, you'll need to
change the case.
It'd be nice if --version wasn't so wordy or you could get just the version
like uname -r
