The liens for work and labor done or things furnished, as specified in sections 429.010 to 429.340, shall be upon an equal footing, without reference to the date of filing the account or lien; and in all cases where a sale shall be ordered and the property sold, which may be described in any account or lien, the proceeds arising from such sale, when not sufficient to discharge in full all the liens against the same without reference to the date of filing the account or lien, shall be paid pro rata on the respective liens; provided, such account or liens shall have been filed and suit brought as provided by said sections.
