comparison inside [[]] is not numeric comparison?

[john.ruckstuhl]

In bash, a comparison inside "[["/"]]" is lexicographic not numeric?
This isn't what I expected.
Which part of the documentation would set me straight?  If someone
could quote the fine manual, that would be great.

$ if [[ 2000 > 200 ]]; then echo pass; else echo wierd; fi
pass

$ if [[ 1000 > 200 ]]; then echo pass; else echo wierd; fi
wierd

$ set | grep BASH_VERSION
BASH_VERSION='3.2.51(24)-release'

Thanks,
