Can the scale be determined from only this excerpt?
How can the musical scale be identified from the following excerpt? Is it possible?
Is there any scale to have a formula like 1 - 2 - ?3 - 4 - ?5 - 6 - 7? Perhaps a variation of a scale?
The thing is I found a contemporary semi-composotion written atonally and I'm trying to figure out if any corresponding scales could be found. All notes are used with the following accidentals:
I believe it cannot be either B major or B minor.
Please suggest improvements to or directly edit this post for I believe it is flawed.

First of all, your formula is completely wrong. The pattern for 1 - 2 - ?3 - 4 - ?5 - 6 - 7 on B would be B - C♯ - D♯♯ - E - F♯♯ - G♯ - A♯ because those scale degrees are in reference to the major scale. The actual description of this scale using this notation would be 1 - b2 - 3 - 4 - 5 - b6 - b7. A more standard representation of this would be to describe the steps in which would come to H - A - H - W - H - W - W or internals from root which would be m2 - M3 - P4 - P5 - m6 - m7.
There are more scales out there than just major and minor. This scale is the B Phrygian Dominant scale which is a mode of the E harmonic minor scale.
I have a lot of experience with scales so I can identify them on the fly by looking for a few key elements. To be able to do that you need to familiarize yourself with the pattern of the basic scales and modes you come across and recoginze deviations from the typical pattern. For example in this case I noticed it was a Phrygian scale with a major third thus was able to realize what it was.
No. To determine any scale/mode requires two sets of data, only one of which you have provided.
1) The notes of the scale. That is clear. So far, so good.
2) The "key center," meaning the pitch upon which a resolution is made at the end of the phrase.
That second element is unclear. @Dom has assumed that the B is that note, because you placed it first in your example (the traditional place for the key center in a scale example). But I would ask any inquirer specifically if they [you] already know that B is the resolution point for that phrase. And then give the answer accordingly.
I have no doubt that @Dom is correct, given that corroboration. However, the strict answer to the question is "No, a scale cannot be determined from a collection of notes from an excerpt, until the key center is determined."
