Possibly, if you have the uploader 'tuned' for the shortest possible keypresses which still work reliably then even a small amount of extra capacitance could make a difference by rounding off the corners of the keypad scanning signals a bit.

Used in the original way, the job of the joystick was just to deliver static on or off voltages to the joystick interface input so the effect of any cable capacitance would be negligible.

You seem to have found a workaround anyway, but we may have to look to increasing the score from two digits to three if there is any code space left for the code required to do that.
