What's the problem?

Metatags don't (currently) work like that. The search you give above is identical to a search for desc:lore_girly -- the last value given for a metatag is the one used.

This would be more obvious if there were other posts which had only lore_girly.

(this is also confusing, because it means that desc:foo desc:bar and desc:bar desc:foo are completely different searches.)
