Pin13 is also shared with the SPI SCLK clock, which is used by the MicroSD card TinyShield. When you use a SPI device like the SD card, the LED will blink, and the SD library will override the digitalWrite() function call. This is expected behavior, and gives you a way to visually see SD activity as an added bonus!
