Weight Ordering Bug

When the input filters are loaded the filters are sorted by their key name to order them by weight. Unfortunately they key name also includes the module name and delta so the default sort uses string comparisons so you end up with odd orderings (e.g. 10 will come before 2 and -1 before -3). To fix this we need to specify numeric comparisons should be used. This will convert the keys to numbers as documented here: http://www.php.net/manual/en/language.types.string.php#language.types.st...

I've attached a patch for this fix.
