You're using the (very) old & deprecated 4DOS syntax. @SELECT was changed 10+ years ago to take window coordinates (relative to the TCC window), not row/column arguments. For the sake of compatibility with old batch files, @SELECT will assume that a width < 150 means you want rows & columns, and it will take your arguments & multiply them by the font width & height to get the window coordinates.
If you want to be sure you get the right position and size, try using window coordinates (by pixel) instead. Something like:
