Using にしておいてやる to say "Let's pretend"?


> 今日のところは引き分けって事にしておいてやるっ！

I saw this sentence in the dialect of a videogame between character A and B.  
B says this line after being defeated by A.  
I think B is saying that they should pretend this (defeat) is a "tie" (Because
he seems to be arrogant) but I'm not sure how the おいて part shows some kind of
preparation for the future. Would it be ok to omit おいて form the sentence? or
will change the meaning completely.

His entire speech was:

> 「ハァ…ハァ…こんなに熱くなったのは久しぶりだぜ… 今日のところは引き分けって事にしておいてやるっ！
> 今度オレとやる時まで、誰にもやられるんじゃねぇーぞ！じゃー、あばよっ！」




～ておく has [several meanings](https://japanese.stackexchange.com/q/5216/5010),
and in this case it means "to leave (status)" or "to do (something) **for now
/ for the time being** ". 窓を開けておく can mean both "to leave the window open" and
"to open the window beforehand."

So saying ておく here implies he is going to win eventually in the future.
Dropping おく and saying 引き分けってことにしてやる will not largely change the meaning in
this particular case, because he's already said 今日のところは ("for today", "for
now"), which also implies the situation will be different in the future.
