Just an editorial aside -- they're 'major', not 'mayor' ticks...
But, the answer to the question is "no can do" -- there's no addressable property even in later versions for the minor ticks except on|off; spacing is totally determined internally based on spacing between the major ticks. You can't control the number nor the spacing nor query the internal properties programmatically to determine what was done, either. All you can do is to use text at a given location but what that location should be will have to be derived heuristically based on what you can infer from the behavior observed.
