Narrative:

While on descent to 15000', ZMA cleared us to cross 10 NM northeast of lal VOR at 10000' and 250 KTS. At approximately 11300' ZMA asked if we were maintaining 13000'. We replied that we were assigned 10000'. On arrival at mco we called ZMA on the landline and talked to the supervisor for that sector and discussed it with him. The supervisor said he wasn't sure what was on tapes but that 10 NM northeast lal at 13000' was the standard clearance. Supplemental information from acn 148945: the controller said to climb immediately back to 13000', which we did.
