Well you could automate that by using steemjs, get all the comments, look into the text to see if there is a [1] or a [2] inside of it, then check if they indeed voted on your post. If so, execute a transfer to them.

You'll find a snippet to transfer here :

For the rest you can find the functions here :

https://github.com/steemit/steem-js/tree/master/doc

to get the comments on a post use : steem.api.getContentReplies
To get the votes use : steem.api.getActiveVotes
