Does it make sense to order condition in where query? We have a clustered index in table Tbl with order of A,B,C.
Does it make senses to write a query to have

WHERE A = @a, B = @b, C = @c


or it'll be as same as

WHERE C = @c, B = @b, A = @a


Does the order of query make sense for clustered index?
It makes no difference: the optimiser evaluates the query and will work out predicate order for itself, matching a suitable index and all the other good stuff it does.

This is because SQL is "declarative" not "procedural": you say what you want, not how to do it.

It's nicer to read though...
