Don't be fooled by the easy appearance of this riddle. The answer gets you to first base but to get a gold star, you must find and explain all of the clues. It took a good deal of effort to compose this so I intend to make you work to get the answer. If you find twelve or fewer, try it again. My advice would be to take it in stages.

At the end of a tail it's an earmark or flag.
Giving a touch, give it a name
Greatest in code but it's kind of a game
A part of a lace maybe something you spray
Take a gathering back in advantage I say.
