Human Factors
My aircraft; had landed and cleared Runway 27R at Intersection 'R'. Ground control first cleared me to taxi to the ramp via 'B' (parallel taxiway) and 'Kilo'. She then changed her mind and cleared me to taxi via Bravo and Lima (perpendicular to runways) to hold short of Runway 27C. She then (among instructions to several other airplanes); said 'taxi via Lima and Kilo.' I took this to mean I could enter the edge of Runway 9/27 center; and turn right onto Taxiway Kilo one; which is an extension of Runway 9/27 center.  The Tower then told me I had taxied on an active runway without clearance. No conflict with other aircraft occurred. I consider that this deviation was caused by a very busy ground controller giving unclear; confusing instructions. I.e. there is no Taxiway Kilo at that end of Taxiway Lima. Turning left would be a seldom-used Runway 9/27 Center and turning right is Taxiway Kilo One; all the same strip of concrete. An additional possible cause is a ground controller with a slightly foreign; hard to understand accent.
A King Air 90 pilot reports a confusing clearance to taxi via Lima and Kilo while holding short of Runway 27C on Lima at SFB. The clearance is interpreted as Lima and Kilo 1 which is not correct and the reporter is admonished by the Ground Controller for a runway incursion.
