Does it not work if you just set mapcyclefile? Try some like this in your startup...

srcds -console -nocrashdialog -game tf +maxplayers 32 -port 27015 +mapcyclefile cfg/mapcycle.txt +map lolctf2fort

now i know it looks dumb/redundant, but it stopped various map plugins and the game engine from crying about missing mapcycle files.
