Here is a sketch to illustrate what I meant in the previous post. I changed the state change example to work with an active LOW (LOW when pressed) switch. Make a function for each of your sequences to be called by the cases or insert sequence code in the cases.

const int buttonPin = 3;

int buttonPushCounter = 0;   // counter for the number of button presses
int buttonState = 0;         // current state of the button
int lastButtonState = 0;     // previous state of the button

void setup()
{
  Serial.begin(9600);
  pinMode(buttonPin, INPUT_PULLUP);
}

void loop()
{
  buttonState = digitalRead(buttonPin);
  if (buttonState != lastButtonState)
  {
    if (buttonState == LOW)
    {
      buttonPushCounter++;
    }
    lastButtonState = buttonState;
  }
  switch (buttonPushCounter)
  {
    case 1:
      // callsequence one
      break;
    case 2:
      // callsequence two
      break;
    case 3:
      // callsequence three
      break;
    case 4:
      //reset button push counter after 3 sequences. Zero is is the idle state
      buttonPushCounter = 0;
      break;
  }
}
