<tr>
  <td colspan=2 align=right>

Answer 1

I think you are using smarty. Therefore please try using .

 {php}echo rand();{/php}

Answer 2

From the php-docs:

If called without the optional min, max arguments rand() returns a pseudo-random
integer between 0 and getrandmax(). If you want a random number between 5 and 15
(inclusive), for example, use rand(5, 15). 

So better use:

<tr>
    <td colspan=2 align=right>
        <font color=red>*</font>Order ID
    </td>
    <td>
        <input type='text' name='name' value='<?php echo rand(min_value, max value);?>' disabled>
    </td>
</tr>
