Here's the signature for Windows:

"CCSPlayer::SetRank" // MedalCategory_t category, MedalRank_t rank
{
	"library"		"server"
	"windows"		"\x55\x8B\xEC\x81\xC1\xCC\x15\x00\x00"
}

Also for sprays the only thing I know that exists about it that in items_game.txt there are 2 attributes related to sprays but I have no idea how they work.

"232"
{
	"name"		"sprays remaining"
	"attribute_class"		"sprays_remaining"
	"description_format"		"value_is_additive"
	"description_string"		"#Attrib_SpraysRemaining"
	"hidden"		"0"
	"effect_type"		"positive"
	"stored_as_integer"		"1"
	"score"		"8500"
}
"233"
{
	"name"		"spray tint id"
	"attribute_class"		"spray_tint_id"
	"description_format"		"value_is_additive"
	"description_string"		"#Attrib_SprayTintID"
	"hidden"		"1"
	"effect_type"		"positive"
	"stored_as_integer"		"1"
	"score"		"8500"
}
