1. We need to determine the smallest number \( n \) such that no matter how we select \( n \) real numbers from the interval \([1, 2013]\), we can always find a scalene polygon with sides equal to some of these numbers. 

2. A scalene polygon is a polygon with all sides of different lengths. For a set of numbers to form a polygon, they must satisfy the triangle inequality: the sum of any two sides must be greater than the third side.

3. Consider the set of numbers \( \{1, 1 + \epsilon, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024\} \), where \( \epsilon \) is a very small positive number. This set contains 12 numbers. Notice that for any three numbers in this set, the sum of the two smaller numbers is always less than or equal to the largest number. Therefore, these 12 numbers cannot form a scalene polygon.

4. Now, we need to show that if we select 13 numbers from the interval \([1, 2013]\), we can always find a subset that forms a scalene polygon. Assume we have 13 numbers \( a_1, a_2, \ldots, a_{13} \) in increasing order.

5. Define \( S_i = a_1 + a_2 + \ldots + a_i \) for \( i = 1, 2, \ldots, 12 \). We claim that \( S_i > a_{i+1} \) for some \( i \). Suppose not, then \( S_i \leq a_{i+1} \) for all \( i \).

6. This implies:
   \[
   a_1 < a_2
   \]
   \[
   a_1 + a_2 < a_3
   \]
   \[
   a_1 + a_2 + a_3 < a_4
   \]
   and so on, up to:
   \[
   a_1 + a_2 + \ldots + a_{12} < a_{13}
   \]

7. If we sum these inequalities, we get:
   \[
   (a_1) + (a_1 + a_2) + (a_1 + a_2 + a_3) + \ldots + (a_1 + a_2 + \ldots + a_{12}) < a_2 + a_3 + \ldots + a_{13}
   \]

8. Simplifying the left-hand side, we have:
   \[
   12a_1 + 11a_2 + 10a_3 + \ldots + 1a_{12} < a_2 + a_3 + \ldots + a_{13}
   \]

9. Rearranging terms, we get:
   \[
   12a_1 + 10a_2 + 8a_3 + \ldots + 2a_{12} < a_{13}
   \]

10. Since \( a_1, a_2, \ldots, a_{13} \) are all in the interval \([1, 2013]\), the above inequality implies that \( a_{13} \) must be extremely large, which is not possible because \( a_{13} \leq 2013 \).

11. Therefore, our assumption that \( S_i \leq a_{i+1} \) for all \( i \) must be false. Hence, there exists some \( i \) such that \( S_i > a_{i+1} \).

12. This means that we can always find three numbers among any 13 numbers in the interval \([1, 2013]\) that satisfy the triangle inequality and form a scalene polygon.

Conclusion:
\[
\boxed{13}
