Thanks to mchruscielewski for your provided info:

In ActivationCommand, method protected List getOrderingInfo(Content node) builds list of siblings in correct order for reordering after publication, but it will work only if siblings are of the same type. As we can have multiple node types in one content app (like I have here), it cause order problem I experienced.
Please consult somebody if this is expected behaviour, and maybe document it somewhere?
My workaround was to extend activationCommand class and change this sibling type check, to accept all my custom node types.
