It is schemes. Though it comes from the Latin schema, it’s not a Latin word.

Do not confuse this with schema, which is not the plural of scheme, but the singular form of schemata.

“schemas” is also widely accepted as a plural of “schema”. In what I read, it is also much more used. – F'x Jan 19 '11 at 8:47
