Bermudian striker Nahki Wells coolly despatched a shot from inside the penalty area following a rebound in the 19th minute and defender Rory McArdle headed home Gary Jones' cross in the 77th minute to give the npower League Two side an unlikely two-goal lead.
Bradford almost put the tie beyond their top-flight opponents moments later when striker James Hanson headed against the crossbar, but Villa, who spurned a hatful of chances in either half, grabbed a crucial late lifeline through Andreas Weimann before Carl McHugh restored the home side's two-goal advantage with another header two minutes from full-time.
