There's no code to execute a script file in MQL4, but there's a trick:

1- Assign a hot key to the script (Right click the script in the Navigator window and from the context menu choose "Set hotkey").

2- download Send Keyboard keys to MetaTrader!

3- In your EA use the functions:
void SendKey(int key,bool release = false)
void ReleaseKey(int key)
