Fixes error related to ruby 1.8

in ruby 1.8 elements of hashes aren't ordered. This causes puppet catalogs to be nondeterministic and therefor changes are made even when source data has not changed. Sorting the hash fixes this. In newer ruby versions this behaviour is fixed and hashes are ordered by insertion.
