Most Helpful Girl
She doesn't seen really shy, she just probably doesn't want to converse with people that 1. She does but know. 2. Especially with people that she does know. She took an intrest in you, and was hinting that she had plans so you could fix that for her. It I'd possible that she could just be chatting with you, but 1. You said she only spoke to you this way. 2. You are a guy and most girls know that you don't want to here all that, especially a complete stranger. But still I'm pretty sure she was flirting with you, I mean it's not like she just said one random thing, she said 3 and it was all under the same subject, so age was clearly trying to hint something.
I say you go back there, talk to her and ask her out.
