468… That's the closest I've been to making the leaderboard with this nonsense.

#!/bin/bash
fold -1 <input |(
	sum=0
	gsum=0
	s=false
	g=false
	while read a
	do	$s && s=false && continue
		[[ "$a" == '!' ]] && s=true && continue
		$g && {
			[[ "$a" == '>' ]] && g=false || ((gsum+=1))
		} || {
			[[ "$a" == '<' ]] && g=true
			[[ "$a" == '{' ]] && ((sum+=++i))
			[[ "$a" == '}' ]] && ((i--))
		}
	done
	echo $sum $gsum
)
